I see illegal instruction errors when the hardware does not support the instruction set. Still, it's odd to see it during compilation (the compiler will write the instruction regardless of whether your hardware supports it). What processor are you using? What compiler are you using?

Have the same issue. I'm using:
gcc 9.3
12th Gen Intel(R) Core(TM) i7-12700K
Edit:
More info
traps: rdl2_ispc_util[5676] trap invalid opcode ip:7f8919c3a101 sp:7fff63feecf0 error:0 in libcommon_math.so[7f8919c3a000+1000]
from openmoonray.
rdl2_ispc_util is build as with the same compiler flags as the rest of moonray -march=avx2. What flags does your machine support run more /proc/cpuinfo to find out look for the flags: labels and under there look for avx2 fma and f16c.

Thanks @rwoods-dwa that's not supported on my machine

@fjallraven I am almost positive that MoonRay will build and run with avx (avx1, as opposed to avx2), but your machine doesn't support that. I don't know if MoonRay will compile with sse4.2 support, but you can try.
