I can give you very little when it comes to information. Under normal runs
it just hangs, no output.

Trying to attach to a running version from GDB is useless, it just stops the
run, without any semblance of a stack trace, and it can't continue the
execution.

Running it in GDB require turning of some of the signals you are catching.
So after disabling GDB handling of FPE, ABRT, and SEGV I get the infinite
loop of...

The stack trace at this point is the non-informative...

(gdb) bt

(gdb)

So is there something I can do to get you more meaningfull information?
