Allow core file to be saved
# ulimit -c 99999; # unit are in KB
...
# gdb mc core.1234
(gdb) bt
#0  0x40287673 in strlen () from /lib/libc.so.6
#1  0x401933e2 in Gpm_Open () from /usr/lib/libgpm.so.1
#2  0x4032f91d in __libc_ptyname2 () from /lib/libc.so.6

The back trace is different,  the behavior from working again
to segfault is puzzling, at best.

The backtrace being different let me beleive that it is
trigger from a different case.
