That's why I use -mcmodel=large.
Try to build without -mcmodel=large on Cygwin. It might be a problem with crtbegin.o being built for the medium code model used for Cygwin applications by default. If that doesn't work, you'd probably need another set of gcc CRT files built for the large code model. > As far as I understand the error message and as stated by Corinna in > https://sourceware.org/ml/cygwin-developers/2013-04/msg00011.html This is about compiler intrinsics and has nothing to do with your problem, sorry.
