With -fchecking we get:

<source>:23:13: error: type mismatch in 'pointer_plus_expr'
   23 | static void send_document(DESC *d, short err, const char __flash
*err_string,
      |             ^~~~~~~~~~~~~

const struct 
{

  const <address-space-1> char * desc;
  _Bool subst;
}[3] *

sizetype

_5 = &mime_types + _9;
<source>:23: confused by earlier errors, bailing out

This is from laddress.

Can reproduce on x86_64 with __seg_gs will attach the code in a second.

Confirmed. At least for x86_64, it is not a regression.

Possibly also fixed by r14-6133-ge00c00730912cd, confirmed (x86 testcase) on
the GCC 13 branch.  Fixed on trunk.
