How to detect run-time stack smashing/buffer overflow in C and enable gdb to exit gracefully with proper message.?

Question

Buffer overflow is causing gdb to behave in a erratic way and proper logs are not being printed. How to enable gdb to print logs in a proper way?

Also, is there a way to detect runtime stack smashing in a multithreaded environment?

Searched about -lmcheck but it is not thread safe.

How about tools such as [Valgrind](http://valgrind.org/)? – Some programmer dude Sep 17 '14 at 07:04 — Some programmer dude, Sep 17 '14 at 07:04

If you use gcc you may try option -fstack-overflow combined with the valgrind tools.
