https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100146 --- Comment #6 from Jonathan Wakely --- I suppose this would be OK: #if _GLIBCXX_HAVE_USELOCALE # define __cpp_lib_to_chars 201611L #endif

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100146 --- Comment #5 from Jonathan Wakely --- It's std::from_chars which incorrectly allocates. It uses strtod which requires a null-terminated string.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100146 --- Comment #4 from Jakub Jelinek --- The uselocale thing could be handled by defining the macros only if _GLIBCXX_HAVE_USELOCALE. Does any implementation actually handle it without memory allocations? I mean, even sprintf can fail with ENOMEM

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100146 --- Comment #3 from Jonathan Wakely --- No, because std::from_chars still depends on uselocale, and needs to allocate memory (which can fail, yielding an error code that isn't permitted by the standard).
