            Bug ID: 97900
           Summary: g++ crashes when instantiating a templated function
                    with a template-type vector parameter
           Product: gcc
           Version: 10.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: Jonathan.Strobl at gmx dot de
  Target Milestone: ---

Dear GCC maintainers, I have managed to crash the compiler with the following
template instantiation. This happens on version 10.2.0 (on Debian Testing), as
well as on 11.0.0 20201114 (experimental) on compiler explorer:
https://godbolt.org/z/57xYb7

g++ -x c++ - <<EOF  
template<typename T>
T test(T __attribute__((vector_size(2 * sizeof(T)))) vec) {
    return vec[0] + vec[1];
}
typedef int v2si __attribute__((vector_size(2 * sizeof(int))));
int run(v2si vec) {
    return test<int>(vec);
}
EOF


I have attached the output of "gcc -v" as well as the full backtrace. Thank you
very much for your support.

Yours sincerely,
Jonathan Strobl
