Stack memory area print that would show symbols and memory address using GDB

narasimhap · 09-16-2014, 06:48 AM

Hi
I am seeing some stack smashing issue in my program. I have used btrace /where and could see where the problem is. I would like get a complete view of the stack during this issue, to when the stack overflow is happening what all memory areas of my code are getting corrupted How would I do that? The current support with btrace/where just limits to the parameter in scope, but doesn't show the stack overflowen/corrupted area. Please advice.
Let me know if anymore details required.

Thanks
YA

Have you gotten any answers yet.. from anywhere?

I wish I could suggest something more thorough than trace.. but my programming/detective skills are not up to date

.. at least not in the details of memory maps.

How about assembler tools? Might be overkill.. but there might be something there..

I would think.. Linux has a multitude of programs and plugins, that would help solve your request..

Hi narasimhap,

Are you still looking for answers?

If the details of the situation warrant it, have you considered using watchpoints?

If it's appropriate for your situation, have you tried mtrace? mtrace may make use of malloc_hook's which are technically deprecated, but even if it does, if you still have mtrace on your system, you might want to give it a try.

Have you consulted the info doc on gdb? It contains a wealth of information.

HTH.
