box64 Segmentation Fault trying to run Blender 2.79

OS: Ubuntu Mate 21.10 64bits System: Raspberry Pi 4B 4GB #Overclock options: over_voltage=2 arm_freq=1750 gpu_freq=600 gpu_mem=256 BOX version: compiled from box64-0.1.6 source

Trying to run Blender 2.79 (the nighty build version contained in a tar.bz2 that needs no installation) since in the Ubuntu 21.10 repositories only Blender 2.93 is found and can't be properly run in the Raspberry Pi 4B (even using MESA_GL_VERSION_OVERRIDE=3.3) cause the SoC only supports up to OpenGL3.0 and Blender 2.93 requires OpenGL3.3.

I run Blender 2.79 with Box64 and got SIGSEGV error and execution is aborted.

Output generated by Box64:

I got the same errors (along with "Error: Global Symbol qt_version_tag not found") with Quartus. I'll take a look.

It seems TBB was statically linked in Blender 2.79, whereas in my case __RML_open_factory, __TBB_make_rml_server, __RML_close_factory, and __TBB_call_with_my_server_info are in libtbb.so.2:

They all seem to be weak symbols without default definitions, which probably explains the errors. A definition is found when the executable is run on x86_64, however. I have no idea from where they are found yet, but I'll keep on digging. Any hints, @ptitSeb?

Apr 05 '22 18:04 mhavu

The symbols are nowhere to be found, and I'm starting to think they are not actually needed. Maybe the missing global symbols should be warnings instead of errors, and they have (or at least should have) nothing to do with the segmentation fault. @ptitSeb, should the jump table still be correctly built in case there are missing symbols?

Apr 06 '22 06:04 mhavu

Those WEAK symbol are probably optionnal. Yes, I should put a "Warning" instead of an "Error" for Weak GLOBAL_DAT stuff.

When a symbol is missing, it's value is NULL. And if it's indeed optionnal, the program test for NULL value and shouldn't crash. Anyway, I don't think those Error/Warning are the cause of the crash. The segfault is for accessing a non-NULL value. Issue is that pointer value seems "too big" to be correct, I should try on my side to debug this.

Apr 06 '22 07:04 ptitSeb

Indeed. In my case, the segfault comes from accessing 0xfffffffffffffff8, which is clearly too big.

Apr 06 '22 07:04 mhavu

I have tried it on my side, and there is a randomness in the crash, making it diificult to track the bug down. There maybe multiple bugs here also. It's slightly more stable without dynarec (using BOX64_DYNAREC=0), but even there, it crashes eventualy.

Apr 06 '22 09:04 ptitSeb

I tried various software components in the Quartus suite, and BOX64_DYNAREC=0 doesn't seem to have any effect. The components that use Qt seem to segfault when accessing pointer values in seemingly valid range (e.g. 0x2a0000004a):

3027|SIGSEGV @0xffff57841728 (???(0xffff57841728)) (x64pc=0xffff70b12550//home/mhavu/intelFPGA/21.1/quartus/linux64/libccl_mem.so:"/home/mhavu/intelFPGA/21.1/quartus/linux64/libccl_mem.so/Z24mem_register_dll_for_pgoPKcS0 + 272", rsp=0xffff91150be8, stack=0xffff90952000:0xffff91152000 own=(nil) fp=0xffff657d8e80), for accessing 0x2a0000004a (code=1/prot=0), db=0x7b621930(0xffff57841728:0xffff5784195c/0xffff70b12550:0xffff70b125ad//home/mhavu/intelFPGA/21.1/quartus/linux64/libccl_mem.so/Z24mem_register_dll_for_pgoPKcS0 + 272:clean, hash:8dad1db9/8dad1db9) handler=(nil)

This is probably another bug that is not related to the one described for non-Qt software above.

Can this ticket be closed now?

Can this ticket be closed now?

Uhm.... I don't know, I am now on Rasberry Pi OS (Debian 12 Bookworm) and I installed Box86 and Box64 using Pi-Apps, I run Blender 2.79b downloaded from https://download.blender.org/release/Blender2.79/ the program opens, shows correctly the UI, everything seems fine.

But when I try to add a new mesh to the scene, say a simple cube, or try to edit the default cube in the scene, Blender abruptly closes with no messages, exiting a "segmentation fault" in the terminal.
