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
