#1820: Windows segfault-catching only works for the main thread
-------------------------------+--------------------------------------------
Reporter: simonmar | Owner:
Type: bug | Status: new
Priority: normal | Milestone: 6.8 branch
Component: Runtime System | Version: 6.8.1
Severity: normal | Keywords:
Difficulty: Unknown | Testcase: derefnull(ghci), divbyzero(ghci)
Architecture: Unknown | Os: Windows
-------------------------------+--------------------------------------------
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.
