Bug 18547 – Win32: throwing exception in fiber crashes application

test15779.d crashes for Win32 (and Win32/COFF) if compiled without -gx (or with -O): import core.thread; int main() { try { bar(); } catch (Exception e) { } return 0; } void bar() { new Fiber({ throw new Exception("fly"); }).call(); } The auto-tester currently disables it for Win64, though.

The actually used stack can depend on the version of DbgHelp.dll, the existence of debug information and possibly other conditions. https://github.com/dlang/druntime/commit/86cd40a036a67d9b1bff6c14e91cba1e5557b119 Merge pull request #2129 from rainers/issue18547 fix issue 18547 - Win32: throwing exception in fiber crashes application merged-on-behalf-of: Petar Kirov <[email protected]>
