Description
Building with compilers (clang 11, gcc 10 or 11), any version of sld2 on raspberry pi os 32 bit bullseye on a Raspeberry pi 4/400, the game crashs when starting a mission or demo with SIGNAL 7 caught, aborting.
However the game compiles and runs without issue on the same system but with 64 bit OS.

Steps to Reproduce
No response
Can you please compile in Debug and provide a gdb backtrace of the crash? That will help identify the cause. Note we now target mainly 64 bit architectures
Forgot to mention that for the game to compile in raspberry pi os 32 bit I had to change mveasm.cpp. In line 2060 I changed "#define int3 asm volatile("int $3");" to "#define int3". I did this to fix a "bad instruction 'int $3'" error on the Raspberry Pi 4
Does this help?:
Thread 1 "Descent3" received signal SIGBUS, Bus error.

Inferior 1 [process 21289] will be killed.
There is no doubt we have to clean up the x86 specific stuff, so the source code becomes more portable between systems. Though the Apple silicon specific fixes should be helpful for this issue since we are talking about the ARM processor here.
I got the game working without problems on a Raspberry pi 4 64bit recently. 32 bit is not officially supported anymore, we can close this.
