            Bug ID: 44848
           Summary: C++20 template lambda calling another template lambda
                    causes segfault
           Product: clang
           Version: 9.0
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++2a
          Assignee: unassignedclangbugs at nondot.org

Clang crashes when compiling the code below:

int main() {
    auto lambda1 = [&]<bool B>() {

    };

    auto lambda2 = [&]<bool B>() {
        lambda1.operator()<B>();
    };

    lambda2.operator()<true>();

    return 0;
}

It works fine with g++.
