As stated, Blender 2.78 crashes if 'Full Sample' AntiAliasing is checked.

The fix is to uncheck 'Full Sample'.

You didn't archive it, you closed it. This is not productive, although it might look that way.

The reason I logged this incredibly easy to fix problem was for Documentation purposes.

Like most people, when I have a problem I search the Open bugs for work-arounds.

Might I suggest an Unverified status instead? At least then people can see the report.

[If I had wanted to see this very minor problem fixed, I'd have submitted a patch. It
is normal policy to expect developers to know their software well enough to be able
to verify bug reports. Requiring users to submit .blend files really starts to sound
like blaming the victim. This bug is very easy to verify, you shouldn't have needed
a .blend file. In the old days, I'd have sent Camp[bell a patch and it would be checked
in by now. Instead you guys sat on the bug report for months and then demanded
more proof. I'm not impressed. Maybe it's time to cancel my Cloud subscription ...]

Unresponded request from triaging team makes bug invalid, not archived. You’ll be so kind as to either not report bugs, or make minimal required efforts to help us fix them, otherwise you are merely wasting everyone’s time, wich is unproductive and frustrating.

In all fairness asking for a .blend is not a form victim blaming, sometimes it's just easier to reproduce a problem that way, what's always happening to you, might not happen to us, I just tried to reproduce this report, rendered my default cube, Full Sample on, off, didn't matter, rendered with no problem. messed 5 minutes with various options trying to trigger it , couldn't make it happen, Now if I had a .blend that would have crashed as soon as I hit render, I could have spend that time actually fixing the problem. So it's not a 'we don't believe you! prove it!' it's more of a 'help us to help you'

The bug tracker is there for users to help developers make Blender better.
We have clear and friendly guidelines to remind reporters of that. The last line in the guidelines state:

"Bug fixing is important, the developers will handle a report swiftly. For that reason we need your help to carefully construct a case others can redo. You do your half of the work, then we do our half!

For help or support you can use many other websites, such as blenderartists.org forums or stackexchange. See blender.org/support.

What I expected was something like "Thank you for taking the time
to try and make Blender better. We are unable to verify this bug.
Can you either submit a patch or a blend file, or else detailed steps
to be taken to replicate the bug." NOT a Borg-like "Submit a blend
file or we close this bug.". Did anyone apart from LazyDodo even
try to verify this bug?

I was disappointed to see how many bug reports were being
closed due to users not providing blend files. Frankly, I think
this is a huge mistake. People are already reluctant to submit
bug reports and anything that makes this process more painful
than it already is will simply reduce the number of bugs that
get reported. A week might seem reasonable but that's after
over 2 months of inactivity at your end.

In my case I was able to very easily get around the problem,
but took the time to file a bug report in case it was an issue
for anyone else. As this was some time after the fact, I was
not able to supply a blend file or even exact instructions,
but it is pretty easy to reproduce.

@LazyDodo you don't bake an environment map by hitting F12.

If noone can be found who knows how to bake an EnvMap,
let me know and I will see if I can try to remember how.

@Ton it's a bug, that's why I logged it as such. I am perfectly
happy to see unverified bugs being flagged as "Wontfix" or
some such but just because they cannot be verified does not
mean they are not bugs!

@LazyDodo my apologies, you do bake an EnvMap by hitting F12.

Have just re-verified with 2.78a Windows 10 64-bit.

Please let me know if you are not able to verify.

PBR Lighting.blend

Steps to reproduce: F12 to render EnvMap. Enable FSAA (Full
Sample under Anti-Aliasing on the Render panel. Hit F12. CTD.

Thanks for the confirmation and sorry for some of the snark.

I think my problems are really with Phabricator, with Bugzilla
(or whatever you guys used before) it was obvious what you
were there for and there were pulldowns for OS and the like.
And probably a very obvious Upload Attachment button!

Only Blender scheduler active thread seems to be the one running threaded_tile_processor() in pipeline.c, which is awaiting on done work at line 1406, so… AM a bit lost here, does it makes some sense to you?

Problem seems to lie in the constructor of TileBufferTask in e:\db2\S\VS1464D\build\openexr\src\external_openexr\IlmImf\ImfTiledOutputFile.cpp@692

where it copies a pointer from TiledOutputFile::Data * (ofd) info an DeepTiledOutputFile::Data * (_ofd) which doesn't match the struct layout, and things go down hill from there.

Note: the FSA flag (incl exr temp buffer saves) in the main scene should be cleared in the renders of the environment map. If crash doesnt happen without envmap render, it's there.
