Hi,
How good is the threading support in Free Pascal? I'm using 2.1.1. I
haven't used threading before under FPC and am about to revamp an
in-house application to support mutliple threads. I don't want to
start the app and then find out that there is some major stability
issues with threading

The test project /fcl/tests/threads.pp
I see random alteration of a and b here.
The threads.pp test project in fcl, shown a lot of a's on the screen
and after a while, starts displaying b's on the screen. Looking at
the source, I gather the a's and b's are supposed to be mixed as each
ok, I see hundreds of a's - press b and quite a bit later I see
hundreds of b's.
Do you have lazarus? I can then post the Sort Demo to show that one as well.

Attached is the Sort Demo - for incase you have Lazarus.

Just to give some more feedback. Using that same Sort App, I compiled
it under Delphi 7, and ran it under Linux using WINE and the threading
worked correctly. So somewhere in FPC or Lazarus lies the problem.
Yeah I know, not very specific. :-)

Can you try running
The only FPC/Lazarus for windows I have is under the same VMWare
session as I used for Delph 7. And yes it works there, using FPC
2.0.2 with a Lazarus 0.9.15 (9152). I'll be at home in a hour, so
then I can try under FPC 2.1.1 and latest Lazarus.

So far using FPC 2.0.2 and 2.0.4 and latest Lazarus (svn) it works
fine under Windows. I am now busy building FPC 2.1.1 (svn) under
Windows and will redo the whole process. Will post the result
shortly

This seems to only be a problem under Linux. Threading works fine
under Windows (via WINE or native), but is screwed under Linux native!
Under Linux, it has been tested with 2.0.4 and 2.1.1 (I saw no point
testing it

I have tested this on 4 different machines all with the same outcome.
Is any body else using threading in their applications? Are you
experiencing the same issues under Linux? If so, I
What is also very interresting, which I thought I would share. I
added three more Bubble Sort columns to my test app (total of 6 sort
threads - knowing bubble sort is the slowest).
I then created all 6 threads suspended (t1 thru t6 in order). I then
resumed the threads in the order t1, t6, t2
