Broken: Blender 2.80 (December 11, 2018 - hash - win64)
I have an object with a Multiresolution modifier and sculpting on it.
When I try to go to the Edit mode Blender instantly crashes.
This happens every time, no matter what project I'm working on.
The error message from the command prompt stays the same every crash.
Error Output from command prompt:

I'm getting something similar with the mirror modifier - adding the modifier and then going to edit mode crashes Blender, as does being in edit mode and then adding the modifier.
When this happens, the console prints

containsBlender 2.8 (9a8b6d51c12) - Crash when going in Edit Mode with Multiresolution modiferto Blender 2.8 (9a8b6d51c12) - Crash when going in Edit Mode with Multiresolution modifierThat's interesting. I've only experienced this problem since I swapped out the Subdivision modifier with the Multiresolution modifier to allow much better sculpting.
Must be a problem with all modifiers that store specific information about the original and the modified mesh then.
I did a super-quick test (add the modifier to the default cube; hit tab; see if it crashes) with all the modifiers (there might be a few that slipped through if they needed a setting changed before they started doing anything or something)
The modifiers that caused Blender to crash for me were:
Here's the error log from that testing.
Funny how you list the Subdivision Surface at the modifiers that caused your Blender to crash, but apparently having the Multiresolution got working since it's not on your list...
while at me, it's the exact opposite:
Edit mode with Subdivision Surface = No problem
Edit mode with Multiresolution = Dead
But at least I can confirm that the other modifiers that you've listed are also causing crashes.

broke it.

@capnm I can't get it to crash here. Are you sure you can repro with latest 2.8 (from git)?
@fclem Yes, e.g. just open the file F5916342 The bisect log:
It opens fine here. All the commit you bisected are from yesterday.
That's in the Europe today ;-)
The last commit without crashes was
Blender still crashes here right now when you open that file ¯_(ツ)_/¯

I just recompiled Blender and it seems to be working fine - build hash

Can confirm that

Reproducible here e.g. with the file from #59183:
