--- Comment #1 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Seeing basically the same thing building the linux kernel on microblaze-elf:
typedef unsigned int size_t;
struct strarray {
char **array __attribute__((__counted_by__(n)));
size_t n;
};
char **devm_kasprintf_strarray(struct strarray *ptr)
{
if (!ptr->array)
return ERR_PTR(-12);
}
Compile with -O2:
j.c:8:2: internal compiler error: in build_unary_op, at c/c-typeck.cc:5790
