           Summary: crash at goto label inside sizeof
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal

source.cpp:
int main() {
    sizeof(({M:0;}));
    goto M;
}
output:
clang-8: error: unable to execute command: Segmentation fault (core dumped)
clang-8: error: clang frontend command failed due to signal (use -v to see
invocation)
clang version 8.0.0 (trunk 346454)
Target: x86_64-unknown-linux-gnu

Code is a little strange... gcc gets sigsegv too :)
