Summary: dependent operator name in template function argument
type crashes clang
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++0x
AssignedTo: [email protected]

This causes clang to segfault:
template<typename T> void operator_(decltype(operator T)) {}
template void operator_<int>(int);
The crash is here:
