John ANDERSON reported a new bug.

Summary
-------

Setting Breakpoint controls if errors messages are emitted or not

Type             : Bug
Priority         : High
Gambas version   : Master
Product          : Development Environment


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

Attached is a project (with known repeatable error) where if you set a breakpoint near end of code:  If you let program run to completion after breakpoint, errors are emitted to console.  No breakpoint ==> No error messages emitted.

That should -never- happen.  If there is an error at code completion, then error message should -always- be printed.  If not, no error message should be printed, regardless if breakpoint used or not.

Otherwise: we would never know of potential code problem if we didn't use breakpoint?.  Or could we be wasting time tracking down an allocation error that was just due to breakpoint itself?

That has us suspicious of Gambas error trapping - if it happens on this project, where else is this going to happen?  OR maybe there isn't a real critical error in code, maybe it is a core problem with Breakpoint?  

And what are "Unfreed allocations" and why are there 10 of them in this case - it would be nice to have a little more details on that printed on error message if possible.  If possible it would be good if Gambas told us what the actual objects are that aren't being freed, and then we could look more closely at where the objects are declared and used...and are we supposed to free them ourselves?  The docs don't seem to have a lot on this subject.
