Your report is scarce of detail. Perhaps there is a bug in your program? Another possibility is that GMP does not work right on Ios. Since that is a closed platform where developers need to pay Apple for programming, you cannot excpect any effort from the GMP team with regards to development or testing of GMP for Ios. If somebody who pays the Apple programmer tax is willing to help you debug your crash, we will certainly look at whatever GMP change might be needed. -- Torbjörn Please encrypt, key id 0xC8601622 ___ gmp-bugs mailing list gmp-bugs@gmplib.org https://gmplib.org/mailman/listinfo/gmp-bugs

Ah, Good catch.
Using host `aarch64-apple-darwin` gives me "unknown AArch64 fixup kind!"
errors.
