#3288: GC assertion failure in reactive program
-----------------------------+----------------------------------------------
Reporter: Baughn | Owner:
Type: bug | Status: new
Priority: normal | Component: Runtime System
Version: 6.11 | Severity: normal
Keywords: | Testcase: crash.hs
Os: Unknown/Multiple | Architecture: Unknown/Multiple
-----------------------------+----------------------------------------------
In the same vein as [http://hackage.haskell.org/trac/ghc/ticket/3279 bug
#3279], this time I've triggered an assertion failure in the GC by adding
Debug.Trace.trace expressions.
The exact same failure occurs in both 6.10.3 and 6.11, apparently
completely deterministically.
A darcs patch to add the crash to reactive, and a program to trigger it,
are both attached.
Expected output:
{{{
sv...@eris ~ $ ./crash
<Imp NoBound 2.0,1.0>
<Imp NoBound 2.5,2.0>
<Imp NoBound 3.2,3.0>
<Imp NoBound 3.7,4.0>
"never-never"
crash: internal error: scavenge_one: strange object 28
(GHC version 6.11.20090605 for x86_64_unknown_linux)
Please report this as a GHC bug:
