--- Comment #4 from David Binderman <dcb314 at hotmail dot com> ---
I get something similar for this C code:
enum fmt_type parse_num_range(const enum fmt_type);
enum __attribute__((packed)) fmt_type {
FMT_NUMBER_OF_FORMATS
} parse_number(const enum fmt_type) {}
$ /usr/bin/gcc -c -g bug877.c
$ ~/gcc/results/bin/gcc -c -g bug877.c
bug877.c: In function ‘parse_number’:
bug877.c:4:27: error: type variant differs by TYPE_PACKED
4 | } parse_number(const enum fmt_type) {}
| ^~~~~~~~
<enumeral_type 0x7fc8f09b4348 fmt_type
type <integer_type 0x7fc8f0821348 unsigned char public unsigned QI
size <integer_cst 0x7fc8f0802e88 constant 8>
This error seems like a regression in gcc-13.
The bug first appears sometime before 9b111debbfb79a0a.
