Here's a short PIR program that demonstrates the problem:
$ cat x.pir
.sub 'main'
.local pmc arr
arr = new 'FixedPMCArray'
arr = 4
arr[0] = 'just'
arr[1] = 'another'
arr[2] = 'perl'
arr[3] = 'hacker'
## called with normal Sub, works
$P0 = get_global 'cmpfn1'
arr.'sort'($P0)
$S0 = join ' ', arr
say $S0
## called with MultiSub, fails
$P0 = get_global 'cmpfn2'
arr.'sort'($P0)
$S0 = join ' ', arr
say $S0
.end
.sub 'cmpfn1'
.param pmc a
.param pmc b
$I0 = cmp_str a, b
.return ($I0)
.end
.sub 'cmpfn2' :multi(_, _)
.param pmc a
.param pmc b
$I0 = cmp_str a, b
.return ($I0)
.end
$ ./parrot x.pir
another hacker just perl
No applicable methods.
