--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
diag_attr_exclusions() expects either a DECL or a TYPE but here it gets an
expression:
$ gcc -S pr94346.c
pr94346.c:8:33: internal compiler error: tree check: expected class ‘type’,
have ‘expression’ (compound_expr) in diag_attr_exclusions, at attribs.c:396
8 | ATTR (copy ((bar (), ((struct A *)(0))[0]))) int m;
| ^
pr94346.c:1:35: note: in definition of macro ‘ATTR’
1 | #define ATTR(...) __attribute__ ((__VA_ARGS__))
