Hi Pieter,

I have tried just using the new libraries (both 3.2 and 4.0), but it seems
that the wrapper I'm using is doing something that is not allowed.

The error I get when using 3.2.3 for example is:
Assertion failed: check () (msg.cpp:191)

Anyway, thanks for the comment, it was reassuring. I'll keep digging.

All the best,

Kevin
