I use this in some of my testing code (don't forget the -rdynamic):

#include <execinfo.h>
#include <iostream>

#ifdef _EXECINFO_H
void show_stackframe()
{
	void* trace[ 64 ];
	char** messages = NULL;
	int trace_size = 0;
	
	cerr << "Begin Stack Frame Dump" << endl;
	cerr << "(if useful symbols are not found, try recompiling "
		<< "with -rdynamic during link, and -g without -O#)"
		<< endl;
	trace_size = backtrace( trace, 64 );
	messages = backtrace_symbols( trace, trace_size );
	for( int i = 0; i < trace_size; ++i ) {
		cerr << "Traced: " << messages[i] << endl;
	}
	cerr << "End Stack Frame Dump" << endl;
}
#endif 
// _EXECINFO_H
