trying to debug a bad pointer error [1 Attachment]
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? -- ------ Matt D ------------
All you need to do is run: gdb core.8995

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!
