1820,Windows segfault-catching only works for the main thread,simonmar,,"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.",bug,new,lowest,7.6.2,Runtime System,6.8.1,,,,Windows,Unknown/Multiple,None/Unknown,Unknown,"derefnull(ghci), divbyzero(ghci)",,,
