Not for me on FC4. The process size grows to about 180M and the system
thrashes badly, but the calculation runs to completion.
It's not unlikely that we are ignoring a failed allocation somewhere,
but there's not much hope of finding it from the available
information. You could try running under gdb and see where things go
wrong for you.
