Wasn't it already failing?

Huh, no, the failure is new for LE.

--- Comment #3 from seurer at gcc dot gnu.org ---
char to_chars_buffer[output_length];
auto result = to_chars(to_chars_buffer,
to_chars_buffer+output_length,
value, fmt, precision);
VERIFY( result.ec == errc{} );
VERIFY( !memcmp(printf_buffer, to_chars_buffer, output_length) );
Dumping out the values of things on the VERIFY that fails I see
output_length: 8
printf_buffer: 1.000000
to_chars_buffer: 0???????
There is another PR for the long_double test cases but that is something
different unless this fix triggers the other thing.

I did see the failure, but thought it was due to PR 98384.
Fixed now, and with Patrick's r11-7378 it also passes for -mabi=ieeelongdouble
