Hi,
The attached program works well under Linux when compiled with Kylix3. It
counts from 1 to 10 and ends. FPC compiles it, but doesn't work (loops
forever). Seems that CheckSynchronize doesn't work (or perhaps
TThread.Synchronize?).
Another issue: CheckSynchronize has in Kylix3 an optional parameter (Timeout:
Integer = 0), not available in FPC.
Regards,
Pedro
