[gcc tip] Function backtrace in the program code

be sure that you link with -rdynamic flag

#include (execinfo.h)

void print_trace()
{
const size_t max_depth = 200;
size_t stack_depth;
void *stack_addrs[max_depth];
char **stack_strings;
int i;

stack_depth = backtrace(stack_addrs, max_depth);
stack_strings = backtrace_symbols(stack_addrs, stack_depth);

for (i = 1; i < stack_depth; i++) {
printf("%s\n", stack_strings[i]);
}

free(stack_strings);
}
