#14310: Assertion triggered by STM invariant. ----------------------------------+-------------------------------------- Reporter: mbw | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.4.1 Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4065 Wiki Page: | ----------------------------------+-------------------------------------- Comment (by bgamari): Unfortunately I'm still seeing occasional assertion failures with the patch. Frankly, I'm very confused by the treatment of invariants in `stmCommitTransaction`; it seems to me like we will happily proceed with committing a transaction (and touching invariants) even if we aren't able to lock all invariants (see the `break` around line 1350 of `STM.c`). This seems quite suspicious. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14310#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
