Ok rlimits was next on my list.

However something seems strange here.  Your Ram was ~512M.  This
should have yielded a value of 64M for ggc-min-heapsize.  Your
memoryuse is set to ~470M.  And yet your compilation died allocation
up over 64M.  Why is this?

Is there some other rlimit set lower than RSS?  Can you show me all of
the rlimits on your system please?  (Especially RLIMIT_DATA.)

Can you also please reissue the compile with -v and tell me what the
GC heuristics are?
