[Bug classpath/22827] jamvm/kaffe crash with unknown locale

[gcc-bugzilla at gcc dot gnu dot org]

When there is LANG value which is not locale-gen'ed,
both kaffe and jamvm crash.  I'm not sure whose bug it is.
If its VM bug, I can report it further.

public class Test3 {
public static void main(String [] args) {}}

$ LANG=vi kaffe-cvs Test3

The crash with JamVM is a bug in the VM, and I suspect it will be the same with
Kaffe.

If the value is not locale-gen'ed, setlocale appears to return null.  I do
basic checking that the returned locale string is in the right format, but not
for null!

A fix will be in the next release.  If anybody requires it, I can submit a
patch.  Thanks for finding this.

Guilhem Lavaux just told me that the bug is fixed in Kaffe CVS.

The first fix wasnt enough, but now its ok.

If rlougher says that jamvm is ok too, then I guess thus bug can be closed.

Works for me now with the latest kaffe (CVS) and jamvm.
