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

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?
