Heap-use-after-free error on exit of debug build (in Audaspace area)
Closed, ArchivedPublic

Description

System Information
Operating system: Debian testing 64bit

Blender Version
Broken: current master, debug build with ASAN enabled.

Short description of error
Every time I close my debug build (gcc 8.2.0, asan enabled), I get a heap-use-after-free error.

Exact steps for others to reproduce the error

SUMMARY: AddressSanitizer: heap-use-after-free (/usr/lib/x86_64-linux-gnu/libasan.so.5+0x96e3f)

Note that is one comment or move above the NULLDevice::registerPlugin(); line in AUD_initOnce(), then error is same but on OpanAL plugin or so, so it looks lkie it's the last item in the device mapping that triggers the issue.

Have no idea whether there is actually an issue in audaspace itself, or if this is a weird glitch/bug from either the compiler, or std, or… :(

Bastien Montagne (mont29) triaged this task as Normal priority.

@Joerg Mueller (nexyon) Assigning to you for now, guess you'll be more familiar than me with c++/templates/std weirdness. ;)

I tried reproducing - I enabled WITH_COMPILER_ASAN (and disabled cycles and libmv in order to get it compile on my machine) but I only get memory leaks when I run blender then, not the error you reported. Do you have any hints on how to reproduce it?

I'm running arch linux with gcc 8.2.1.

Hrrrmmm… Well, I do not use WITH_COMPILER_ASAN either, it does not work very well for me… So I rather just edit the CMAKE_C/CXX_FLAGS_DEBUG flags in cmake, and add -fsanitize=address to both.

If you still cannot reproduce, then I wouldn’t be surprised if this was an glitch somewhere in the compiler/stdlib area, too… I will try later with gcc9, see if I still have that annoying thing. :)

Just tried with setting it in C/CXX FLAGS but same result as with WITH_COMPILER_ASAN. Please let me know what you get with gcc9. If you still have it there, I fear you'll have to help me debugging this. ;)

Unfortunately gcc9 is not actually installable in debian testing currently (there are some unstable packages, but broken).

On a side note, also getting some memleak report when using Cycles (just rendering default cube), in DeviceInfo area. Looks somewhat similar to Audaspace one to me (memleak from a call to a vector.insert()...)?
