Comment:
It's possibly related to this bug, but I'm not sure.
Today my program has just died with the following message:
textmining-zajecia04_05-zad1 +RTS -K100m -s -A30m -hT -N
textmining-zajecia04_05-zad1: internal error: heapCensus, unknown object:
58
(GHC version 7.0.2 for x86_64_unknown_linux)
Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug
It fails reliably after doing ~30s of work, the '58' number stays the same
in each run. The error goes away if I disable the -N switch OR -hT switch.
I'm runnign Linux, Arch Linux distro - up to date with LLVM 2.9, the
building is -fllvm with a ton of flags.
