Running standalone on 64 bit Linux

[David Beck]

Hello everyone,

I am having some very weird, inconsistent and difficult to track 
problems running a LiveCode standalone on a 64 bit Linux machine with a 
32 bit compatibility layer. As far a I can tell, the wierdness is 
associated with tricky things like regular expressions and getting "the 
value of" expressions. These problems do not occur on a 32 bit box, and 
then I run the same standalone on a 64 bit box and there are these weird 
problems that I can't reproduce. Two questions:

1. Since what version of LiveCode is running a standalone on a 64 bit 
Linux box (w/ 32 bit compatibility layer) officially supported?
2. How likely do you think it is that these problems are associated with 
the 64 bit environment? How "solid" are compatibility layers ?

Thanks very much for any help!
