this library causes requesting a Socket to send the Java VM (1.1.6) into
a thread panic aborting with many errors and traces. if the library is
replaced with the older ld-linux.so.1.9.5 library the problem goes away,
but breaks other programs on the system. Is there a better fix for this
problem? If the Socket is opened using the ld-linux.so.1.9.5 library
then the newer library is put back in using ldconfig, the Java program
will still work.
The Errors I get follow, a sample the simple program that generated them
is after the errors.
ERRORs:
SIGSEGV 11* segmentation violation
stackbase=0xbffff850, stackpointer=0xbffff754

Any help on this would be appreciated.
