64-bit statically linked binary consumes all memory while spinning on 'SIGVTALRM's
I actually have no idea if this is a haskell bug or not, but since the earlier reported symptoms are similar, and the "pandoc" program is compiled with GHC, I thought I would report it here as well.
This situation sounds exactly like this bug reported 17 months ago.
Symptoms are 'pandoc --version' hangs and consumes memory until the process eventually dies with an OOM error. This seems to only happen when LC_ALL is set in the environment, and only when running the statically linked pandoc.

Note this problem does not occur if I run an older dynamically linked pandoc under the same circumstances.
