The preprocessed dump from the error.
The following code fails with a segmentation fault:
#include <memory>
template<typename T>
using CallbackPtr = const std::shared_ptr<const T>;
template<typename C, typename T>
using CallbackFunPtr = void (C::*)(CallbackPtr<T>);
int main () {
return 0;
}
[matt test] g++ --std=c++11 -Wall -Wextra -Werror -pedantic -pedantic-errors
main.cpp
main.cpp:7:49: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugzilla.redhat.com/bugzilla> for instructions.
Preprocessed source stored into /tmp/ccuw4zjD.out file, please attach this to
your bugreport.
However changing CallbackFunPtr to:
template<typename C, typename T>
using CallbackFunPtr = void (C::*)(const std::shared_ptr<const T>);
It's OK.
