Contrived example:
void function ()
{
std::terminate ();
}
int main ()
{
}
(gdb) start
(gdb) call function ()
Breakpoint 0, 0x00007ffff7992110 in std::terminate() () from /usr/lib
^^^^^^^^^^^^
/libstdc++.so.6
The program being debugged entered a std::terminate call, most likely
caused by an unhandled C++ exception. GDB blocked this call in order
to prevent the program from being terminated, and has restored the
context to its original state before the call.
To change this behaviour use "set unwind-on-terminating-exception off".
Evaluation of the expression containing the function (function())
will be abandoned.
(gdb)

This is related to the momentary breakpoint at std::terminate being
of bp_breakpoint kind.
