(In reply to comment #4) Works correctly on my x86 PC and produces error on amd64 laptop. On which architecture you run it?
my amd64 desktop
Works fine after upgrade to gcc-4.6.3
I had such problems when I had two migw32-g++ installed: 4.5 (active) and 4.7. For some reason 4.5 had empty libstdc++. 4.6.3 seems to produce binaries, but they are broken. Even simple <iostream>y "hello world" produced by 4.6.3 dies before main() (somewhere in sjlj.dll loader). Binaried built winh 4.7.1 look and run fine.
