However, when I try to compile the simplest source with on older gcc-3.4.4 I get the link error below, but only for the threaded rts!
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. Cheers, Simon
