Ticket #5953 (closed bug: wontfix)
Program execution fails with runtime error.
Description (last modified by igloo) (diff)
I ran a very memory consuming program on a 32GB machine with the following RTS arguments:
-H18000M -S -c
hoping that I could avoid all the copying. However, I got the following message:
internal error: update_fwd: unknown/strange object 27330425 (GHC version 7.0.3 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug Abort
As a side note: with just the -c option, I had run into a Segmentation Fault.
Without any run-time options, the programs fails to complete succesfully before running out of memory.
