--------------------------------+-------------------------------------------
Reporter: MikolajKonarski | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 7.3 | Keywords: MVAR_CLEAN
Testcase: | Blockedby:
Os: Linux | Blocking:
Architecture: x86_64 (amd64) | Failure: Runtime crash
--------------------------------+-------------------------------------------
How to reproduce:

cabal install Allure --ghc-options="-dcore-lint -debug" -fvty
$HOME/.cabal/bin/Allure
then press '.' a few times. (If nothing happens, press Q and try running
it again.)
Allure: internal error: MVAR_CLEAN on mutable list
GHC version 7.3.20110803 for x86_64_unknown_linux)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Aborted
Without the debug options it segfaults much less often. I does not
segfault at all, to my knowledge, when compiled with 6.12.3 and 7.0.*,
even with the debug options. Neither of the other frontends (-fgtk nor
-fcurses) compile with 7.3 right now, so I couldn't test those, but it may
be informative to check them, as soon as the gtk2hs and/or hcurses
libraries are updated to compile with 7.3.
