You may get better answers if you specify which platform you are
using, which version of the compiler, etc.

Try setting breakpoint on __cxa_throw.

It sounds as if you (or some code you link to) installed non-default
terminate handler, which printed above message.

Default terminate() should have aborted the program, at which point
gdb should have told you where that's happening.
