Hi,
I did a very basic fuzzing attempt and found a segmentation fault. The following code crashes both with gcc and clang:

#include <fmt/core.h>

int main() {
float item=9.57489014e-4;
std::string message = fmt::format("\x7b\x3a\x2e\x30\x7d", item);
}

It also crashed for double (not necessarily with the same number), suspect it is the same issue.
