[Bug middle-end/33279] New: Failed to warn uninitialized stack variable

["hjl at lucon dot org" <gcc-bugzilla at gcc dot gnu dot org>]

[hjl@gnu-26 uninit-2]$ cat x.c
typedef int mpz_t[1];
typedef struct iterator_stack
{
  struct iterator_stack *prev;
  mpz_t value;
} iterator_stack;
iterator_stack *x;
void bar (mpz_t);
void
foo ()
{
  iterator_stack frame;
  bar (frame.value);
  x = frame.prev;
}
[hjl@gnu-26 uninit-2]$ make
/export/build/gnu/gcc/build-x86_64-linux/gcc/xgcc
-B/export/build/gnu/gcc/build-x86_64-linux/gcc/ -O2 -Wuninitialized -S x.c


It seems that gcc is confused by

typedef int mpz_t[1];
