Program no longest exists?

Program no longest exists?

[Alvin Beach]

Hello all,

I have recently upgraded from suse 9.1 to suse 9.3. Since upgrading, I can no 
longer debug programs that I was able to debug before.

When I run gdb, the program runs fine as long there are no breakpoints. As 
soon as I set a breakpoint and run the program, I get message:

	Program terminated with signal SIGTRAP, Trace/breakpoint trap.
        Program no longer exists.

Sometimes it happens right away, sometime after I step over the breakpoint.

I have found reference from googling that this may be pthread related? My 
programs do use pthread.

Is there a work-around or fix for this. Without gdb, my programs are no 
littered with cerr/printf statements.

Thanks,

Alvin

Unfortunately, they don't. I guess I will just have to wait until they do. In 
the meantime, I'm going to look for a way to dump a stack trace (like in KDE 
when an app crashes - which is happening a lot for me). 

Thanks for the info.

This is usually a bug in your kernel; maybe SuSE has an update kernel
available.
