The argument `%p` to `test_store_capture` can point to errno.
You can't assume all accesses to errno are exactly 32 bits wide. (They usually
will be, but if, for example, someone writes `(char)errno`, we'll narrow the
load.) It's probably okay to assume accesses wider than 32 bits don't access
errno...
