New description:
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:

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.
