Hi

I'm just starting out trying to learn assembler, using HLA and the
"Art of Assembler". I am having problems executing very simple demo
programs.

A hello world program works, however as soon as I introduce a
variable, I get a segfault. I have given a working and broken example
below.

Apologies if I have done something stupid(!) , but any help would be
appreciated. Please let me know if you need anymore information to
help...

Kind Regards
David

Just tried it with v1.97 and it worked without producing a seg-fault.
So this is a bug that was introduced sometime between then and v1.99!
