Other questions:

 * Is your CPU-specific compiler flags properly set ? Maybe they were
   slightly wrong but working with gcc 4.3, and they no longer generate
   appropriate code for your CPU with gcc 4.6. What is your CPU ? What
   CPU-specific compiler flags are you using ?

 * Did you try to do 'ulimit -c unlimited' before running one of those
   binaries, and then inspect the resulting core file ?
