Hi,

The bug has been fixed in the last commit.

A stupid one-line bug that as usual took a day to decipher.

By the way, your use of extern functions was correct.

Returning a pointer and assigning it to a structure is the same as 
returning a structure for extern functions.

It does internally the same thing, creating a special Gambas structure 
object whose contents points at the memory location of the pointer.
