Windows segfault-catching only works for the main thread
On Windows, the RTS tries to catch segmentation faults and divide-by-zero exceptions using structured exception handling in rts/Main.c
. Unfortunately this only works for the main thread, so if the exception occurs in another thread it won't be caught. GHCi runs all its computations in a separate thread, hence derefnull(ghci)
and divbyzero(ghci)
are failing.
