Java programs are easy to debug, one who catch an exception can print the stack trace, and when it crash, it would print the stack, too. It is useful, so I wrote some code of stack_trace for C++, see the sample below:
The trace_scope_stk template here: http://boost.cvs.sourceforge.net/boost-sandbox/boost-sandbox/boost/utility/trace_scope_stk.hpp?revision=1.1&view=markup is related. I've not used it in quite a while; so, the following description may not be entirely accurate. To use it, us must declare an instance of the template at each scope entry. When the program runs, it prints an indented message when entrying the scope and again when exiting the scope. The indentation reflects the depth of the call stack. The elements in the call stack are also stored in a stack which, I'd expect, you can print out somehow. Just from a brief glance at your code, it looks like you also have to put some code at the start of each scope entry and I guess the code pushes something onto the stack (line and file number) which can then be printed when an exception is thrown. It would be nice to merge these two.
