            Bug ID: 113480
           Summary: avr: internal compiler error: in add_dwarf_attr, at
                    dwarf2out.cc:4503
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

This is a relatively new ICE that I see on the avr target.

Compliled with "version 14.0.1 20240118 (experimental) (avr)"

$ avr-gcc pr83801.c -g -O3 -std=3Dgnu99 -mmcu=3Datmega128

/* { dg-options { "-std=3Dgnu99" } } */
/* { dg-do run { target { ! avr_tiny } } } */

__attribute((noinline,noclone))
char to_ascii (unsigned i)
{
    static const char __flash code_tab[] =3D "0123456789";
    return code_tab[i];
}

int main()
{
  if (to_ascii (2) !=3D '2')
    __builtin_abort();

  return 0;
}

I am not sure if it's related to address-spaces, but there are fails that d=
on't
have ASes like gcc.target/avr/torture/pr109907-2.c (but that has __int24
though).
