#145 Executables from 3.50 crash on 64-bit system

[Joel Uckelman]

I have a user who can reproduce a crash every time with a launcher executable produced with 3.50, but never has a crash with a launcher executable produced the same way with 3.14. The breaking commit is fa9a7cbd.

I can't troubleshoot further myself because I can't rebuild head.o in a way that Launch4j can link correctly. I'd be happy to continue troubleshooting if I could get some assistance with doing that.

The thread where I've been working with this user is here.
