Okay, so your code has been segfaulting at line 123 in complicated_func.cpp, and you want to know to which version of libc you have to roll back to as well as related packages if any.

What's the current processor temperature, EPS12V voltage, and ripple peaks if you have a oscilloscope? Could you paste cpuinfo? Have you added or removed RAM or PCIe device recently? Does the chassis smell and look normal, no billowing smoke, screeching noise, fire?

Good LLMs might start asking these questions soon, but you wouldn't supply these information at the beginning of interaction(and it's always the PSU).
