Mea culpa, that is hex. So yes, it probably is just that.

It was just an issue with libtool not knowing how to handle that compiler/OS 
combination really, I've got a feeling that newer releases handle it (or at 
least we may have fixed it internally) but that was fairly recent and so we 
have to live with the reality that there's a bunch of codes now that are 
statically linked.

At least now we have an idea about why it is going wrong (see previous posting 
about the missing environment variable.

We have in the past, but GM is now just in bug fix mode rather than new 
features so the extra code to track memory allocations doesn't really figure 
in their plans (and I can't say I blame them!).

cheers,
