I hit this curiosity when I built quakespasm [1] for x64 using gcc-7.5.0 against mingw-w64 v5.x branch: Hitting longjmp crashes when built using -fno-asynchronous-unwind-tables gcc switch but works properly without it. Anyone has any insight into this? (And yes I know that the v5.x branch is old but the toolchain has been available.)
Is it because that `longjmp()` unwinds the stack on Windows x64, but not on x86 or other operating systems?
