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?
