The formatter for pointers was casting to uint64_t which sign extends a 32-bit pointer and produces a value that won't fit in the provided buffer. Cast to uintptr_t instead. There was also a bug in the __parse_integer helper when converting a wide string to a narrow string in order to use std::from_chars on it. The function would always try to read 32 characters, even if the format string was shorter than that. Fix that bug, and remove the constexpr implementation of __parse_integer by just using __from_chars_alnum instead of from_chars, because that's usable in constexpr even in C++20. libstdc++-v3/ChangeLog: PR libstdc++/110239 * include/std/format (__format::__parse_integer): Fix buffer overflow for wide chars. (formatter<const void*, C>::format): Cast to uintptr_t instead of uint64_t. * testsuite/std/format/string.cc: Test too-large widths. |
