Never seen something like that. Maybe someone else has an idea?

MPS uses SIGXFSZ and SIGXCPU to suspend threads.  So I guess you used
make-thread somewhere.  Under gdb, you can do the same as for SIGSEGV:

  handle SIGXFSZ nostop noprint pass

and it should "just work".

Ouch. Indeed, that makes sense.
