[lazarus] CVS Updated

[Shane Miller]

I haven't been successful in reproducing the error in a minimal amount of code.  One reason for this is that I still don't believe that that's the problem.  Here's what I discovered.

If I take line 339 and copy it before line 337 (both are NOT commented out) then it will crash, but if I leave it the way it is (337 before 339) then it works fine.  

Try it, Copy and move line 339 in front of 337 and open controls.pp.  It'll crash.  

If the line "Writeln('Buffer, Texts '+buffer[i]+'----'+texts+'-');" executes before (or without) 
line "Writeln('Length ='+Inttostr(Length(Buffer)));" then it crashes.  
If they both execute, but the second one (length ='+inttostr(Length(Buffer[i])))'); )  executes before the first it'll be fine.  Wierd huh?

Hope I didn't confuse anyone.  
Michael can you use this to solve the problem instead of me creating another source file with the problem?  I'm not sure I'll be able to create it again. (not on purpose anyways)  :-)

Make MINIMAL code that reproduces this, and we'll fix it ASAP.

And by MINIMAL I understand a standalone program that can be compiled
with the minimum of neede units. I.e. no FCL, GTK etc.
(just trying to lure you out of 'compile lazarus, line .. in ..' :-) )

Florian has done a MAJOR overhaul of the ansistrings code, but apparently, not
everything has been fixed yet :(

Michael.
