Andreas FRÖHLKE reported a new bug.

Summary
-------

Segmentation Fault regarding &= and many controls on the form

Type             : Bug
Priority         : Medium
Gambas version   : Unknown
Product          : Unknown


Description
-----------

We get a SegFault if we use &= operator with a global defined variable and have many controls on the form.
I can provide an example source-code to reconstruct the error, if needed.

We found some workarounds:

 * reduce the count of controls on the form
 * use a variable dimensioned in the current function
 * use "var = var &" except of "&="
