Windows exception handler change causes segfault with API Monitor
API Monitor is a debugging tool that intercepts and logs calls to DLLs. It was extremely helpful with debugging #12010 (closed) and is broken in recent GHCs. Attaching it to a GHC compiled executable causes the message
Segmentation fault/access violation in generated code to be printed. Launching one from inside API Monitor doesn't work either, though I can't read the console output before the window closes. Bisect shows the offending commit is 5200bdeb - "Replaced SEH handles with VEH handlers which should work uniformly across x86 and x64".
I know this is somewhat outside of "standard usage", but there are very few useful debugging tools for stuff like this and I'd really like to not lose this one.
