[Bug c++/60612] Throwing exception, catching and rethrowing (std::exception_ptr) in destructor leads to segfault
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60612 Jonathan Wakely redi at gcc dot gnu.org changed: What|Removed |Added Status|UNCONFIRMED |NEW Last reconfirmed||2014-03-21 Ever confirmed|0 |1 --- Comment #1 from Jonathan Wakely redi at gcc dot gnu.org --- In C++11 destructors have an implicit noexcept, so the 4.7 behaviour is wrong: the program should call std::terminate() when the exception leaves ~A() If you change the program to: ~A() noexcept(false) then it runs and exits normally. If you explicitly add: ~A() noexcept(true) then you get the same behaviour from 4.7 and 4.8, it segfaults in the terminate handler.

--- Comment #4 from Jonathan Wakely redi at gcc dot gnu.org ---
When I step through std::rethrow_exception() in gdb it goes from line 215 to
line 223, so skips over the call to get_terminate(), so dep-terminateHandler
is null and so is dep-unwindHeader.exception_cleanup
(gdb) bt

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60612 --- Comment #5 from Jonathan Wakely redi at gcc dot gnu.org --- *Sigh* -- ignore that. After line 223 it jumps back to 216 then continues back to 223 again with the right values in *dep. I thought I was debugging an unoptimised libstdc++.so but apparently not.
