This suggests that the segfault happens when the GC runs. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10994#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Just as a test I compiled GHC unregisterised to see if it still segfaults like that (which would give me a backtrace), but it doesn't segfault when compiled unregisterised. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10994#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I've done a code review and the only thing I can find which is obvioulsy not what you intended is the function `getPageSize`. I think you meant something like: {{{ static StgWord getPageSize(void) { static StgWord pagesize = 0; if (pagesize == 0) { pagesize = sysconf(_SC_PAGESIZE); } return pagesize; } }}} I'm willing to do a lot of the legwork on getting this fixed but would appreciated nudge in the right direction. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10994#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
