| Did you use the right GC heuristics parameter, e.g. my compiler gives:
| GGC heuristics: --param ggc-min-expand=47 --param ggc-min-heapsize=32007

You may have a point: I didn't those parameters under GDB.
What is interesting to note that a recyling free list apparently
makes GCC consume more memory than just keeping on allocating.
