I've just updated and recompiled everything to r24204 (which did break
binary compatibility) and the test suite passes and my GSWeb apps also
work fine for me.

Maybe you just need to recompile due the ABI change.  If not, what are
the results of the base test suite?

I'd check with ldd to make sure that you only have one version of -base
linked against your application and any frameworks/libraries you are using.

If that doesn't help, please try to confirm that the array which
_gnu_process_args creates here:

  /* Copy the evironment list */
  {
    NSMutableArray      *keys = [NSMutableArray new];

is actually a GSMutableArray.  This array should implement addObject:
directly, i.e. it doesn't rely on:

+ (void) initialize
{
  if (self == [GSMutableArray class])
    {
      [self setVersion: 1];
      GSObjCAddClassBehavior(self, [GSArray class]);
    }
}
for this particular method.  But maybe something else has corrupted the
dispatch tables of class.  But that's going to hard to determine via E-mail.

Cheers,
David
