I'm not so familiar with this part of GMP, but it looks like a bug to me. I would suggest first changing the ASSERT at https://gmplib.org/repo/gmp/file/tip/printf/repl-vsnprintf.c#l355 to ASSERT_ALWAYS; it seems rather dangerous to pass format specifiers we're not understanding to the system's vsprintf. And to really fix this issue, we'd also have to actually support hex floats with %a and %A. Looks like the file was written by Kevin Ryde two decades ago. I wonder if it's possible/reasonable to replace with gnulib's version? That's a few thousand lines of rather non-trivial code, though: https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/vasnprintf.c;h=ab11ad026ed1b5d224dd71a8c880a30d859339cb;hb=HEAD Regards, /Niels -- Niels Möller.
