Description:Code to implement ast_backtrace() which prints a stack backtrace to the logs.


REQUIRES that code optimization be set to -O1 or lower.  WILL NOT WORK at higher optimization levels.

Oh, I should note that this is specific to platforms which are using glibc (i.e. Linux).

Do we need to wrap +#include <execinfo.h> in an ifdef as well?

By: Tilghman Lesher (tilghman) 2005-09-10 17:34:50

Oh, probably.

Maybe change the

ast_log(LOG_WARNING, "Must compile with gcc optimizations at -O1 or lower for stack backtraces\n");


"Only works on Linux with gcc optimizations at -O1 or lower for stack backtraces"

oej:  ast_backtrace() will never be used in CVS.  It is simply there to allow us to obtain easy backtraces during a debugging session.

Changed patch to take advantage of the 'dont-optimize' Makefile target, and added a more meaningful message for non-Linux platforms.
