3956,GHC6.12.2-RC1 runtime error: Invalid object in isRetainer(): 32,jlouis,,"Against GHC6.12.2-RC1:

Running Combinatorrent, version g2a3dff0 with retainer profiling +RTS -hr -RTS produces the following bug:

{{{
This is Combinatorrent ☠ version v0.1.1-180-g5334c4f

I can't select the 6.12.2-RC1 as the version with this problem in the drop-down list. The version of combinatorrent with v0.1.1-180-g5334c4f, publicly available at

http://github.com/jlouis/combinatorrent/commit/5334c4f767970b2bd697ab9e86bdf66258b54de7

can reproduce the problem: Run ./Combinatorrent +RTS -hr -RTS foo.torrent (which doesn't have to exist) to get the above error message.

This is also a regression: Last known version that works with retainer profiling: GHC 6.12.1, if you want to bisect the problem.",bug,closed,highest,6.12.2,Runtime System,,fixed,GHC6.12.2-RC1 Retainer Profiling isRetainer(),,Linux,x86_64 (amd64),Runtime crash,,,,,
