Tested on windows with skipping releasing the temporary memory,
which holds the array of strings (array=malloc(); GetUTFChars() /
ReleaseUTFChars() / free()).

This 'works' ..

It seems that the NV driver executes the glTransformFeedbackVaryings()
out of order, ie access the string array after returning the call.
Since we release the temp memory right away, this will cause the observed
issue.

Trying with new 258.96_notebook_winvista_win7_64bit_international_whql.exe
driver .. same thing.
