Good. Now, if I can have a little bit more of your time, I have two main
curiosities: can you guess why the same 4.4.x *.so + headers don't lead to a
crash with ICC? Then, we should of course come to a possible fix: the idea
would be checking at configure time that the underlying glibc is recent enough
(is 10.1 ok?) and then marking STB_GNU_UNIQUE some selected exported symbols?
The static allocated ones? I'm guessing a bit...
