Not sure if this is 10.14 Mojave error, or my specific computer gone wonky.
Now on 10.14, any use of a TThread has a fatal instant crash, both in Cocoa and Carbon. Project was all OK in older 10.13 OSX.
I only have one iMac to work with here. I tried the latest svn of FPC... no joy. Attached is a bare bones test app. Could someone please compile and run this on 10.14 and report back. press the button - success or crash.
Many thanks
