GMP is built with the options: CC=/home/titouan/Softs/gcc-arm-none-eabi-10-2020-q4-major-x86_64-linux/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-gcc ../configure CFLAGS="-nostartfiles --specs=nosys.specs -mcpu=cortex-m4" --host=arm-none-eabi --disable-assembly --prefix=YOUR_CHOICE As you might guess, GMP's mod operation has been tested a lot during GMP's 30 years of existence. A completely fundamental bug like the one you observe is of course still possible, but incredibly unlikely. It is much more likely that the compiler you used for compiling GMP is buggy. That's indeed where you should start looking. Unfortunatly, we cannot help. We don't know what compiler you used, and even if we did, we don't have access to it. -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ gmp-bugs mailing list gmp-bugs@gmplib.org https://gmplib.org/mailman/listinfo/gmp-bugs
