            Bug ID: 82167
           Summary: Segmentation fault when dereferencing the address of
                    an array argument
           Product: gcc
           Version: 7.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: felix.von.s at posteo dot de
  Target Milestone: ---

Result of running gcc -v -S on the source code given

Attempting to compile the code below triggers a segmentation fault in the
front-end.

int main(int argc, char *argv[]) {
        __builtin_printf("%zu\n", sizeof(*&argv));
        return 0;
}

I discovered this when I was searching for a way to locally silence
-Wsizeof-array-argument (without necessarily knowing if a variable was declared
as an array in the first place), in relation to my comment under bug #14557. Is
there any way to do that, by the way?
