Oh for the coredumps, just gdb pooo.core
A 'bt' will get you the backtrace and you'll see where it took a dump

Sometimes you can see what's up without having symbols but sometimes
you just gotta have built the offending apps with symbols for this to
do any good.

Actually the problem is trying to get a core file to run GDB on ;-)

I haven't been able to find it online and recompiling the basic GTK program
with full debugging symbols (-ggdb3) doesn't get it to dump core. Just
running it in GDB does show a crash pretty darn fast though:

Terry@Dixie$ gdb helloworld

..... copyright stuff
(gdb) break 1
Breakpoint 1 at 0x8048994: file helloworld.c, line 1.

(gdb) generate-core-file

No clue if it's the proper way to get one but hey I guess it's a core file
^_^

The port gtk-qt-engine crashs if you don't run KDE.

This is only a warning from the gtk-qt-engine. I've sent a patch to the
author that use the libkvm instead of procfs.
I don't know why but gtk-qt-engine always crashs if you don't run KDE.

Oh I've never tried saveing core dumps in gdb - cool!

I fear we've reached the point where I don't remember how to talk gdb
into playing with threaded processes (I don't think it's diffcult).
I'm older than dirt, dude, those days when we walked uphill to school
both ways in the snow we were a lot more virile and wanted to fork()
everything in sight, or when I was buds with Methusulah we'd just run
a commutator. We didn't have any of this fancy dancy threading stuff.
In other words please share your progress
