terminal output from failed invocation
clang-5.0.0 will segfault when compiling the following four line template
struct specialisation fragment via `clang++ test.cpp`:
// start
template <>
template < typename a >
struct b<> : a
b () {
// end
The code fragment was produced via creduce from an actual segfault in a larger
codebase. Optimisation level does not appear to be important. Syntax errors are
correctly reported prior to the backtrace.
I'm attaching runscripts, processed sources, and logs. Let me know if there's
anything further I can add.</pre>
