It pretty much the behaviour one gets from g++ by default without doing
anything fancy:
#include <stdexcept>
int main() { throw std::logic_error("empty rule"); }
produces exactly the same output.
I guess somewhere in the OP's program someting similar happen. Just
grepping the sources for the literal "empty rule" might already point to
the "interesting" location.

An uncaught exception in this case...
