Hi,
When compiling i did 'configure --enable-debugging'.
so the memory error finally crashed op25 and the core file dumped. i
ran 'sudo gdb /home/matt/OP25_GRC/op25_grc.py /home/matt/core.8995'.
I hardly got anything out of gdb (i attached a copy of what was in
terminal) but it did say the /home/matt/OP25_GRC/op25_grc.py was not in
executable format: file format not recognized.
What am I doing wrong here?

Hey,
i ran that command. So looking at frame 8 in the backtrace, like Steve
said, it seems that the bad pointer is coming from
'snapshot_du_handler::handle'. or somewhere proceeding there. so i did
'list' and 'info locals' for frame 8 till frame 18. please have a look
at the attached file.
i rebuilt gnu radio with --enable-debug so i am currently waiting for
another crash. kind of funny, hopping the program dies sooner than later.
Thanks!
