Re: [isabelle] isabelle build -vb runs out of store

Hi Andreas.

Not that I know of. PolyML should run in 64bit mode. How do I find out?

In the meantime, I found the reason for the large memory consumption: A
tactic was running amok, recursively instantiating a schematic again and
again, creating larger and larger terms. This was easy to fix, and now
everything runs fine again.
