"internal compiler error: Segmentation fault" WSL Ubuntu

I had the same issue as mentioned in #2905 and it seems that my case it's related to system instability, I forced lowering the cpu speed on my bios (just by disabling "Intel Turbo", I know I have to manual tune voltages and stuff if I don't want to run a potato, but I'll do it eventually) and that did the fix..

I'm a professional IT admin, and this is exactly why I never use overclocking...

I reinstalled windows and then tried to install python again with pyenv and it still fails.

This is an internal compiler error. Try a different compiler version.

gcc -c -fno-strict-overflow -Wsign-compare -DNDEBUG -g -O3 -Wall    -std=c11 -Wextra -Wno-unused-parameter -Wno-missing-field-initializers -Wstrict-prototypes -Werror=implicit-function-declaration -fvisibility=hidden  -I./Include/internal  -I. -I./Include -I/home/carter/.pyenv/versions/3.12.1/include -I/home/carter/.pyenv/versions/3.12.1/include -fPIC -DPy_BUILD_CORE -o Objects/typevarobject.o Objects/typevarobject.c

My cpu is overclocked so it's probably the same issue. I ended up just using windows pyenv and not using wsl.

hey just wanted to add to this - I also experienced this on Windows 11 - WSL - i9 14900k. The culprit was the default motherboard setting "asus multicore enhancement" which is enabled by default. Changing this to disabled solved the problem. However, I never experienced a crash in Windows with this setting on and that included running cinebench, VR workloads, and compiling with Visual Studio 2022.
