I can reproduce this on Arch Linux every time, along with other semi-random crashes. Starting/restarting the game engine also occasionally crashes Blender for me. That happens a lot more on my desktop computer than my laptop. My desktop has an ATI/AMD graphics card, and my laptop has an Intel graphics card. They are both running Arch.

I'm also on Arch 64 and have this problem too for some time now, on my own compiled Blender-master. Crashes/segfaults consistently, not only when moving an object to another layer, but also when subdividing and then increasing the cuts. Downloading from builder.blender.org does not have these crashes.

Hi, I'm the Blender package maintainer in Arch. I fixed our package by forcing -O1 for now and it seems to work. This is obviously not preferable. I'm pretty sure this isn't anything Arch specific but rather a new property to gcc 4.9's optimizing options. I'm not sure which optimization causes this and I can't really investigate as well as you guys could.

This is a bug that eventually all other distros will run into once they finally upgrade to gcc 4.9 and should be fixed by Blender. Using -O1 is not a fix, only a workaround.

@svenstaro, hi, I use arch for my main workstation, seems massing a NULL string (%s) to vsnprintf functions is cause of crash.

eg:

   printf("%s\n", NULL);

Note. previous fix was wrong, committed a correct fix (bad use of nonnull attribute)

This is only a compile-time test for the most trivial cases. Some similar bugs could remain hidden. And maybe many other builtins are affected.

@totoro-4, not sure what you mean. Incorrect use of nonnull attribute can cause crashes, but I checked for other similar cases to this and couldn't find any.

As https://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html says, the nonnull attribute is only a simple compile-time test. I'm sure it can find a NULL only if the argument is a constant (even through a variable etc. but its origin must be a static const). The side effect is at the optimization: the compiler gets a (maybe false) info that the argument is surely not null and uses this to simplify the code. Sometimes this means removing important null checkings. What if the function with the attribute actually can accept null as an argument (@svenstaro 's example is memmove() with zero length: obviously won't crash with a null) and the new optimization policy causes hardly detectable bugs.

Maybe this is okay and not a serious problem anyway. Also I hope gcc will find a better way to optimize in the next version (for example not removing explicit null checkings).

@totoro-4

As far as I can see, GCC is correct and blender was wrong.

GCC uses nonnull to tag a variable as never being NULL.
Blender incorrectly marked all args to BLI_sprintfN as nonnull.
GCC optimized out a NULL check later on (after that argument was passed to BLI_sprintfN)

I'm certain of this because I double checked this and found if (data_path != NULL) { printf("%p", data_path); } ignored the if check and printed 0x0.

Though it would be nice if GCC could optionally warn of redundant NULL checks.
