Just a d too much. In the first case the run of (main 10000) just went
through and didn't cause a heap exhaustion while the second one was on a
machine with way less memory and address-space (64bit 8GB RAM vs 32bit
1G RAM) and showed the hep exhaustion error.

I guess so. The end of the log is below:
