Comment(by msabramo@…):

 Sample output for an actual crash:

 {{{
 RoxorVM::pop_current_exception (vm.cpp:3607) - Warning: Assertion about to
 fail: ((size_t)pos < current_exceptions.size()); pos = 1;
 current_exceptions.size() = 1
 current_exceptions[1]: "#<NoMethodError: undefined method `[]' for
 nil:NilClass>"
 Assertion failed: ((size_t)pos < current_exceptions.size()), function
 pop_current_exception, file vm.cpp, line 3616.
 }}}
