Kai, can you have a look what happens here?
Thanks,

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.
Done. Likely a problem with -freorder-blocks and unwinding-info:

Just for info: g++ 4.8.0-2 works as expected, 4.8-pr56742.patch was
effective.
Smartmontools now works with -O2 or -O3, even with -flto.
Thanks,
Christian
