With ghc-6.12.1 and gcc-4.x.y (x< 3) I did not have such a problem when
switching to a machine that only has gcc-3.4.4.
You got lucky; mixing GCC major versions like that is not expected (much
less guaranteed) to work in general. GCC evidently changed the way it
implements some thread support routines between gcc3 and gcc4.
In particular, thread-local variables, which are used by the parallel GC.
