    I tried to use the bigprone-signal-handler check to find signal safety issues, but it didn't find any, even when I added `malloc(1)` into my signal handler. Looking closer, it seems to check for `signal()` calls, but not `sigaction()` calls: https://github.com/llvm/llvm-project/blob/c4160343741731680359feb2652aa9e4d2376e31/clang-tools-extra/clang-tidy/bugprone/SignalHandlerCheck.cpp#L356-L357
