New description:
lexicals can't be found in nested .subs.
the following works in parrot, but the generated bytecode doesn't seem to
work:
{{{
.sub main
.lex "x", $P0
$P0 = new "Integer"
$P0 = 42
foo()
.end
.sub foo :outer("main")
$P0 = find_lex "x"
print $P0
.end
}}}
So, apparently, lexicals are not stored correctly.
This needs fixing.

Comment(by bacek):
This is output of sample from description.
{{{
~/src/parrot (master)$ ./parrot lex.pir
42
~/src/parrot (master)$ ./parrot -o lex.pbc lex.pir
~/src/parrot (master)$ ./parrot lex.pbc
Null PMC in say
current instr.: 'foo' pc 21 (lex.pir:10)
called from Sub 'main' pc 13 (lex.pir:5)
}}}
