Getting the backtrace from the catch block

You might be interested in a Boost library under development: Portable Backtrace. Example:

#include <boost/backtrace.hpp>#include <iostream>int foo(){    throw boost::runtime_error("My Error");    return 10;}int bar(){    return foo()+20;}int main(){    try {        std::cout << bar() << std::endl;    }    catch(std::exception const &e)    {        std::cerr << e.what() << std::endl;        std::cerr << boost::trace(e);    }}

Prints:

My Error0x403fe1: boost::stack_trace::trace(void**, int) + 0x1b in ./test_backtrace0x405451: boost::backtrace::backtrace(unsigned long) + 0x65 in ./test_backtrace0x4054d2: boost::runtime_error::runtime_error(std::string const&) + 0x32 in ./test_backtrace0x40417e: foo() + 0x44 in ./test_backtrace0x40425c: bar() + 0x9 in ./test_backtrace0x404271: main + 0x10 in ./test_backtrace0x7fd612ecd1a6: __libc_start_main + 0xe6 in /lib/libc.so.60x403b39: __gxx_personality_v0 + 0x99 in ./test_backtrace

Hope this helps!

I don't think so. When executons stops in catch block the stack is unwound, and all that has happened before is not in stack anymore.

Do the classes in question share a common base you can edit?

Otherwise, I provided a wonderful but terribly underappreciated answer at How can some code be run each time an exception is thrown in a Visual C++ program? ;-P Some others opined too.
