icc-10.0 32bit imcc crash

parsing config_lib.pasm crashes. I'll step into it.

emerge strace

with strace it seems to be that the idb debugger is broken, and that's an IO problem only.

As of r48416 (and earlier, but I don't know for how long) Parrot builds and tests 100% with 32bit ICC on Ubuntu 10.04. I see no evidence that the issues raised in this ticket are a problem any longer. Closing ticket.
