If I read the documentation correctly, Cygwin/64 use the LP64 model (as on linux) rather than the usual LLP64 model on windows which is not supported by PARI. So you should be able to build 64bit PARI binaries that will run on windows which is great news! This is probably a compiler related issue. Either the compiler generates wrong code or the PARI code is not standard compliant at some point. If you use './Configure -g' for debug mode, do you get the same error ? If you have a debugger, you can try to provide a backtrace by setting a breakpoint on pari_err_INV() or pari_err(). Which version of PARI are you building ? Which version of gcc are you using ? You can check here the list of systems and compilers we test: <http://pari.math.u-bordeaux.fr/buildlog.html> Cheers, Bill.
