--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I assume that int8_t is char on Solaris, rather than signed char?
Formatting a char behaves differently from signed char, and other integral
types.
I think this will fix it:
--- a/libstdc++-v3/testsuite/std/format/functions/format.cc
+++ b/libstdc++-v3/testsuite/std/format/functions/format.cc
@@ -365,7 +365,7 @@ test_minmax()
s = std::format("{:b}" , std::numeric_limits<U>::max());
VERIFY( s == '1' + ones );
};
- check(std::int8_t(0));
+ check(std::make_signed_t<std::int8_t>(0));
check(std::int16_t(0));
check(std::int32_t(0));
check(std::int64_t(0));
That causes the lambda to use signed char instead of char, and that is
formatted as an integer not a character.
