gdb misbehaviour

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

While trying to update pkgsrc glib-networking on -current/amd64,
I saw that gio-querymodules kept dumping core. I don't understand
the gdb output:

quantz# gdb /usr/pkg/bin/gio-querymodules  
GNU gdb (GDB) 7.12
...
(gdb) break main
Breakpoint 1 at 0x401438: file gio-querymodules.c, line 132.

Program received signal SIGSEGV, Segmentation fault.

"return 0;" didn't? (This is a 20 August system)

Cheers,
