segfault with macro

Arguably, this could either print out 0 and stop, or it could complain about a bad label.

Currently, it segfaults.

(While macro taken verbatim from hllmacros.pir)

$ more foo.pir
.macro While(conditional, code)
.label $beginwhile:
    unless .conditional goto .$endwhile
  goto .$beginwhile
.label $endwhile:

.sub main
.While($I0 < 3, {
say $I0
goto .$endwhile
inc $I0

  • owner changed from whiteknight to chromatic
  • milestone changed from 2.0 to 2.1

The segfault is in IMCC due to a missing label name; confirmed with 2.0.0. I can poke at this.
