NPE with gcc 3.4 when trying to open a tcp-socket

Hy,
I just build gcc 3.4 from cvs, and compiled an application. But this app 
crashes with an NPE right at the start (when it tries to open a tcp-socket):
Exception in thread "main" java.lang.NullPointerException

this does _not_ happen with gcc 3.3
This is not directly related to the topic above, but if i link my files 
with -static, the application segfaults.
Do i have to look for something special when linking static with gcj-build?
