#15060: outofmem testcase sometimes crashes on i386 -------------------------------------+----------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.3 Component: Runtime System | Version: 8.2.2 Resolution: | Keywords: ci-breakage Operating System: Unknown/Multiple | Architecture: x86 Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4704 Wiki Page: | -------------------------------------+----------------------------------- Changes (by bgamari): * differential: => Phab:D4704 * milestone: 8.6.1 => 8.4.3 Comment: Ahh, I see what is happening here. `mmap` returns `ENOMEM` yet then we nevertheless try to `madvise`, which clobbers `errno`, giving us the unexpected `EINVAL` error. Consequently we don't detect this to be an out- of-memory error. Fix in Phab:D4704. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15060#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
