It should not, because checking an overflow is impossible in C, AFAIK. It 
would take far longer to check it than doing the operation. 

So I prefer let the programmer do the conversion explicitely.

I need a piece of your project that raises the bug, and the way to reproduce 
it. Otherwise I cannot do anything.

You can help by running your project with valgrind and a gambas compiled from 
sources, and send me the valgrind output until the crash.
