[fpc-pascal] fpc webassembly and node

[Michael Van Canneyt]

Hello,

Either list is fine.

This should compile and work.

I'm using webassembly and classes quite a lot, even with threading, 
so I see no reason why this simple code should not run.

How did you start the webassembly ? 
How much memory did you provide to the webassembly ?
Did you use pas2js to start it ? What browser did you test ?

Michael.
