It turned out to be a package I had converted from Delphi and installed 
in the IDE. It has System.IsMultiThread:=true in the initialization 
section. Commenting this out eliminated the crash.

What does this property do, and what are the effects of commenting it 
out? The cross platform package uses threads and apps that use it must 
use -dUseCThreads (in Linux).
