The only way to do that would be using a debugger.

The specifics of the solution would thus depend on the platform. 
On POSIX, it would probably mean getting gdb to print a detailed 
backtrace for your project. On Windows, you might be able to 
achieve this by spawning a thread which then uses dbgeng.dll to 
get a detailed stack trace.
