Cool - thanks!

It says 7.2. Probably I should get a newer version. Some output:
  0x0000000100001674 <+308>:   mov    $0x0,%ecx
  0x0000000100001679 <+313>:   callq  0x10000dcc0

  0x0000000100001693 <+339>:   callq  0x100001710 <PRINT>

Which seems to be totally wrong.

Yes, your output seems to be fine! I'll try upgrading my gdb to a newer 
version - hope this helps. If this is working, then I think we should 
switch to DWARF2 on Win64 and close all related bugs in mantis. ;-)
