I don't think the spec places any restrictions on constructor ordering. 
The problem here is that you get different behaviour depending on 
whether you link with libGL first followed by libpthread (in that case 
libpthread initialises first) or if you link in the other order (in 
which case libGL initialises first). As far as I can see, rtld calls 
the _init sections of each shared library in reverse order with the 
last library linked against being initialised first.
