How to reproduce with gdb:

"""
$ TERM=vt100 gdb -quiet /usr/bin/perl
Reading symbols from /usr/bin/perl... [...]
(gdb) run -I blib/arch -Ilib t/05flags.t 0</dev/null
Starting program: /usr/bin/perl [...]
[...]
Program received signal SIGSEGV, Segmentation fault.
termkey_get_flags (tk=0x0) at termkey.c:565

(gdb) full bt
Undefined command: "full".  Try "help".
(gdb) fullbt

(gdb) bt full

"""

In case you want to retrace with more symbols.  The source file for
termkey.c is at [1] and implies that the perl module is passing a NULL
pointer to the function.
