Thanks
I am on a pedal biking holiday in Croatia, but will look at this when I return.

Hi, everyone.
It looks that I found the way how to cause bug mentioned above. For this purpose I used small GC benchmark for D language run-time and adapted it for Component Pascal with some modifications.
I tested on Windows XP with 2 GB, Windows 8 with 4 GB and in Linux/Wine with 4 GB. On all of these machine I reproduced a bug.
If I use patched version of module Kernel by user luowy from September 2012, a bug didn't reproduced for me.
Please compile and run an encoded module TestGCAlloc1 attached below:

Thanks for this - you and Helmut are so much more organised than me!
Marc's email contains updated versions of
- Dev/Mod/Cpc486.odc
- System/Mod/Kernel.odc
& instructions on how to install these files.
Luowy's email contains a later update to Kernel.odc.
There is a problem with Cpc486. The problem involves mixing INTEGERs & LONGINTs, and has been discussed here more than once.
The fix is to add one line; this fix was provided by Louwy on 19-Dec-2011 (give or take a day or two!).
I have just installed Marc's version of Cpc486 + Louwy's INTEGER fix, and Louwy's version of Kernel.
This has certainly helped the Window's 7 memory problem; I have not used it enough yet to know if it is now reliable, but will
report on that later.
Please Oms, is it possible to update the BlackBox page with a version containing a consistent set of known critical compiler fixes?
I appreciate there is no resource to incorporate all the 'nice-to-haves', but a buggy compiler with no easy-to-find, well-documented,
way to obtain and apply critical patches is disappointing.
You said in August last year "..testing a few corrections we made in the kernel and in the compiler. If they turn out to be good, we will release
a new version of BlackBox shortly thereafter."
Thanks, Robert

Robert,
Marc Frei sent an email to this mailing list with a patch attached on 30 Aug
2012.
Luowy followed this up with another modification on 6 Sep 2013 after a
problem with the initial fix
was reported by Romiras on 3 Sep 2012.
I have sent copies of the relevant emails to you,
Regards,
Chris
