Code:
virtual at 0
        some::
        db 'fred'
end virtual

calminstruction bug
        local line ;,val ; no bug with local value
        load val, some:0, sizeof some
        display val ; fredfred
end calminstruction

bug    
... this one took a long time to narrow down. It only happens with "-v 2" command line flag, and when the variable is not local. Encountered it before in larger sources, but it always went away when I tried to narrow it down.

When "val" is not declared as local, the assembly takes 2 passes, otherwise one. The "-v2" switch causes DISPLAY to dump data in real-time, so it shows values from all passes.
