I don't think that's identical.

	msg = (pseudo_msg_t) { .type = PSEUDO_MSG_OP };

zeros out a number of other fields.

Anyway, if it fails with msg declared static, I'd be interested in
a minimal reproducer for it, I don't see anything obvious that ought to
care about it, but I would easily believe that the other fields not
being zeroed out would cause weirdness, which is why I suggested a
complete assignment to it, not just overwriting the .type field.
