[gst-devel] Gdb - help with debbug

[Guilherme]

Hi all.

I finished building my code and it's compiled without any error, but 
when I run it I get the beautiful segmentation fault.

No good.

Running gdb I can't get the line of the problem, instead I have this:

(gdb) run
Starting program: /home/guilherme/EBA
[Thread debugging using libthread_db enabled]
[New Thread 0xb7a479b0 (LWP 5565)]

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xb7a479b0 (LWP 5565)]
0xb7bf2234 in ?? () from /usr/lib/libgstfft-0.10.so.0

Is this a normal debug or I'm doing smth wrong?
It seen a problem with my fft implementation. That is the code:
