libstdc++ 14's <format> initializes a size_t parameter with -1 (GCC bug 119429), so every std::format call fails ci_test_clang_sanitizer under -fsanitize=integer (test-std-format_cpp20). Exclude only the implicit-integer-sign-change check and only that header via -fsanitize-ignorelist. Signed-off-by: Niels Lohmann <mail@nlohmann.me>

# libstdc++ 14's <format> declares `_Scanner(basic_string_view<_CharT>, size_t __nargs = -1)`, so every std::format
|
|
# call converts -1 to size_t, which -fsanitize=integer reports as implicit-integer-sign-change. This is
|
|
# https://gcc.gnu.org/bugzilla/show_bug.cgi?id=119429, not a bug in this library. Only that check and only <format> are
|
|
# excluded, so implicit sign changes in the library and the tests are still reported.
