python@3.8 crashes with illegal instruction message on older CPU #50411

Closed StareInTheAir closed 4 years ago

StareInTheAir commented 4 years ago

What you were trying to do (and why)

I'm running macOS Catalina on no longer supported hardware (a MacBook Pro Mid 2009 MacBookPro5,5) using macOS Catalina Patcher.

When I try to install python@3.8 the post install steps fail and every time I try to run python3.8 it crashes with an illegal hardware instruction message.

When I try to compile it myself with brew reinstall python@3.8 --build-from-source the compile process also fails with a similar illegal instruction message.

What happened (include command output)

Every time I get an illegal instruction message in the terminal, macOS shows an error dialog popup with a more detail exception description:

I googled around a bit and the missing CPU feature probably is AVX (Advanced Vector Extensions) when people get an illegal instruction error while using python. My CPU doesn't have this feature:

% sysctl -a | grep -i features
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 DTES64 MON DSCPL VMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1 XSAVE
machdep.cpu.extfeatures: SYSCALL XD EM64T LAHF

I wouldn't be opening this issue, if python3 (3.7) would show the same error. But the python3 formula works fine on this old MacBook and I can also compile it without errors. MacPorts can successfully install python 3.8 and it runs without problems. But I would really rather use brew instead. This all leads me to the conclusion that it's something in the python@3.8 formula.

What you expected to happen

I expected to be able to compile python@3.8 myself and then being able to run it without the missing CPU features successfully.

Even better would be to have the binary not using the missing instructions, but I see the point of my old hardware holding back everybody else.

Step-by-step reproduction instructions (by running brew install commands)

In the next snippet you can see all my executed commands with their respective output. I also included some more system info.
