Hmm.. apparently that seems to be a a *valid segfault*
based check for upper limit of memory ?.

Btw, slightly offtopic. But a segfault is not always
a cause of worry in pnet when debugging . We have a
NULL check elimination scheme which uses platform
signals to pick up NULL pointers without the overhead
of an if() check & branch :) . If the program is well
designed this is faster as the exception should be for
"exceptional" cases .

It's a good idea to continue until it doesn't go any
further before a BT :)
