yes, this is a gcc bug. it isn't sepcial to cygwin64. It happens also for x64 mingw, so please file a regression-bug in gcc's bz. I will take a closer look about its cause. For me it looks like that unwinding-information doesn't reflect difference in stack-use here, but I will need to investigate in more detail. Thanks, Kai
