GCJ 3.3 crash with string handling reproduceable case

It turns out that the warnings were being generated by the DrMinGW
debugger so we should ignore this.
BTW, I get the exact same error at the exact same location even with
the latest 6.2alpha3 release!
I tried compiling it all using BCC 5.5, but BCC died out on
multiple definition errors in gc_cpp.h (though it should not be...).
Since GCC doesn't support Win32 Structured Exception Handling (SEH),
the README.win32 document paints a pretty bleak picture for it.
:-(

The looking-there-carefully thing didn't yield anything for me, so I'll take
another dekko at it when I am more refreshed, though with only so much
gray matter, there's not much I hope to accomplish...
The Win32 code BTW looks very errr... "weird" what with every #ifdef and
its mother making it difficult to properly understand it. :-(
Ranjit.
