#14081: 8.2.1 runghc from Windows x32 segfaults an all programs ----------------------------------+------------------------------ Reporter: sergv | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.2.2 Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Windows | Architecture: x86 Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ----------------------------------+------------------------------ Comment (by Phyx-):
For some reason crash dumps are not collected, even though I followed
the instructions you linked. I can try building a debug version of GHC and give it a go. Is this the right instructions to obtain debug ghc https://ghc.haskell.org/trac/ghc/wiki/Debugging/Compiler? If you can that would be really handy! as I can't see to reproduce it. https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows are the packages you'll need installed, then just copy `mk/build.mk.in` to `mk/build.mk` and uncomment the `devel2` line. Once building finishes, just do {{{ cd ghc make re2 GhcDebugged=YES }}} and it'll relink ghc using the debug runtime. you can then run ghci as {{{ inplace/bin/ghc-stage2.exe --interactive +RTS -Dl -RTS 2> linker.log }}} to dump a linker log. You can also try attaching it to gdb and see if it happened to have segfaulted in rts code. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14081#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
