Of course I cannot reproduce the issue with a simpler test program :-/
Without a way to test it I can't do anything. So either you need to find
the issue yourself or you need to manage to create a simpler example.
Yes, I know :-(
In my test program I instantiate 4 threads that call synchronize in a
loop (with a Sleep(Random(20)) intermingled), while in the main thread a
TTimer with interval 1 sleeps for 100 ms (to simulate a busy gui).
It's been running for 7 hours already and of course it's still working fine.
In the "real" program I can provoke the issue after some time (ranging
from a couple of minutes to half an hour).
With fpc 2.6.4 it's rock solid (or so it seems), so my workaround is
{$if FPC_FULLVERSION>=30000}
{$ERROR can't use fpc 3.x due to issues with TThread.Synchronize}
{$endif}
(that's just in case I inadvertently open the project with lazarus > 1.6.4)
:-(
Bye
