No, I don't.

Any ideas what I could look at, to determine the cause?

Well, it's for ECL; I don't modify the limits, and the problem happens nearly
reproduceably.

This gets into a (nearly) endless loop, writing some hundred lines.

Sometimes the CTRL-D gives just a segfault; but using gdb just stops, and when
I do "handle SIGSEGF nostop pass noprint" it stops with SIGPWR again.

Any recommendations for this one?
