Hi there,
Good news, it seems :)
On December 16, Robert committed a patch that included the following
lines in FreeTypeLibrary.cpp
if (font) font->setImplementation(0);
fontImplementation->_facade = 0;
However, they are clearly wrong (at least, when the program exits)
because after the first one is executed, fontImplementation points to
unallocated space. Thus setting the _facade to 0 creates the "memory
was modified after it was freed" error.
I have tried to comment out the 2nd line, and the program exits correctly.
As a side note, adding the
osgDB::Registry::instance()->clearObjectCache();
suggested by Jari before the program exists (this would prevent the
problem from happening before my fix trial) does not create any memory
leak. I guess it means that the second instruction above is redundant.
I have also tested the fix in my application, and the error message at
exit went away.
I have not had the opportunity to test on Linux yet because I'm not in
synch with SVN on this platform. Could you guys try this fix in your
various environments ?

You are quite right, I should take the secure route, but as far as I
know, pure C libs have absolutely no problem being used by other
versions of the compiler.
Anyway I'll change my 3rd party libs soon, we never know what
Microsoft will do in the next version of their compiler :)
