my apologies for not replying to your earlier mail, I was hoping to be
able to have some time to look into the issue before replying, but
unfortunately did not get to it yet.
I'll try to take a look at this over the weekend, since I need to
understand how the VRML loader works myself - so I can not really
describe how it works at this point. If you have some specific questions
I'm sure Gerrit (who wrote the parser) would answer them.
In the mean time, since you already seem to have fixed some leaks it
would be very helpful, if you could send a patch for those, otherwise I
would likely end up fixing the same problems first.
Thanks,
Carsten
