contains test.cpp, the stack traces from 3.8 and 3.9, the above text, and the
/tmp files those stacks told me to include with a bug report
I wrote some nonsense code by accident and segfaulted the parser. It's short
enough to fit in here (it's only 8 lines):
__________________________
template <typename T>
class A {
public:
static A<T> const a;
};
template <typename T>
A<T> A<T>::a = A<T>();
__________________________
The parser says it was on the token '=' when it died.
The compiler (specifically the parse step) crashes with this invocation:
$ clang++ test.cpp
Also:
$ clang++-3.9 test.cpp
