--- Comment #16 from David Binderman <dcb314 at hotmail dot com> ---
This C code also seems to generate the same error on 32 bit ARM:
void test_incomplete_array_fam() {
struct FAM {
char c;
int data[]
};
}
void test_single_element_array_possible_fam() {
struct FAM {
char c;
int data[1]
};
}
dcb@raspberrypi5:~/cvise $ /home/dcb/gcc/results.20241114/bin/gcc -w -g -c
fam.c
dcb@raspberrypi5:~/cvise $ /home/dcb/gcc/results.20241116/bin/gcc -w -g -c
fam.c
fam.c: In function ‘test_single_element_array_possible_fam’:
fam.c:12:1: error: ‘TYPE_CANONICAL’ is not compatible

It seems to go wrong sometime between g:361050589b144913
and g:601a734188f3d2d3, so recent gcc trunk.
