#7629: segmentation fault in compiled program, involves gtk, selinux -----------------------------------------------------------------+---------- Reporter: wgmitchener | Owner: simonmar Type: bug | Status: infoneeded Priority: high | Milestone: 7.6.2 Component: Runtime System | Version: 7.4.2 Keywords: segmentation fault, multithreading, selinux, gtk | Os: Linux Architecture: x86 | Failure: Runtime crash Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | -----------------------------------------------------------------+---------- Comment(by wgmitchener): A bit more information: I compiled Try2.hs with ghc -debug --make Try2.hs This is on Fedora 18 with ghc 7.4.1. (FYI: I'm also using the development version of gtk2hs; darcs gives latest patch date of Tue Feb 19 16:39:46 EST 2013). Now Try2 fails with a concrete error message: Try2: internal error: ASSERTION FAILED: file rts/STM.c, line 1476 (GHC version 7.4.1 for i386_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug Aborted which seems maybe to have something to do with not doing one STM transaction inside another? The function where that assertion happens is stmWait. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7629#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
