[Gambas-user] Bug with JIT and external functions

No problem, I'm glad to help making Gambas more robust, when ever I have
time to do so!
And testing things seems to be easy contribution for me...

My project has about 120 000 lines of code. And I try JIT with every module
and class of it.
So I think I will find more bugs... But in some point I must wait support
for callbacks to finish that.
