Hi all!! I am developing an application in GTK, and get in trouble when I have an error. I am using gdb to debug with core dumped enabled.
Sometimes, when I get an error when programming in C , and type in the command line “gdb myprogram core”, I get a trace and the instruction that provoked the exception, but others times I am not able.
How can I know which instruction provoked the exception??
This is an example trace:

I use in my make file the -gstabs tag to compile source code.
Thank you very very much!!
Sometimes, when I get an error when programming in C , and type in the command line “gdb myprogram core”, I get a trace and the instruction that provoked the exception, but others times I am not able.
How can I know which instruction provoked the exception??
This is an example trace:
