I've got the source and tracked that to probably nclose() in tty.c. Other
places where ttclose() or signrm() get called are also in the shell escape
stuff which works without coredump.

It sure did :-) I completely forgot about strace. Too much kernel stuff :-(

It's closed right after opening it and reading it into memory. Don't know what the
SIGALRM are for, they appear at random places even while executing ttclose().
