#5314: "internal error: heapCencus, unknown object: 0" with retainer profiling
-------------------------------+--------------------------------------------
Reporter: akio | Owner:
Type: bug | Status: new
Priority: normal | Component: Runtime System
Version: 7.0.4 | Keywords:
Testcase: | Blockedby:
Os: Linux | Blocking:
Architecture: x86_64 (amd64) | Failure: Runtime crash
-------------------------------+--------------------------------------------
Compile the attached file as:
ghc --make retainer.hs -prof -rtsopts
And run it with:
./retainer +RTS -hr -V0
you get:
retainer: internal error: heapCensus, unknown object: 0
(GHC version 7.0.4 for x86_64_unknown_linux)
Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug
I found this test case while chasing a "Invalid object in isRetainer():
39" problem, so this might be related to the ticket #4820. Also, although
this particular case requires -V0 to reproduce, the original problem
happened without -V0 as well.
