#1826: custom cmp kills FixedIntegerArray::sort

--------------------+-------------------------------------------------------
Passing a custom comparison sub to FixedIntegerArray's sort method causes
a segfault in code that works as expected with FixedPMCArray. The only
difference between the two scripts below is the type of $P0.
{{{
co...@feather:/usr/src/parrot/parrot-svn-committable\ 1 $ cat inner.pir
.sub main :main
$P0 = new ['FixedPMCArray']
$P0 = 3
$P0[0] = 1
$P0[1] = 3
$P0[2] = 3
$P1 = get_global 'sorter'
$P0.'sort'($P1)
.end
.sub sorter
.param pmc a
.param pmc b
say "sort"
.return (a)
.end
co...@feather:/usr/src/parrot/parrot-svn-committable\ 1 $ ./parrot
inner.pir

co...@feather:/usr/src/parrot/parrot-svn-committable\ 1 $ cat inner.pir
.sub main :main
$P0 = new ['FixedIntegerArray']
$P0 = 3
$P0[0] = 1
$P0[1] = 3
$P0[2] = 3
$P1 = get_global 'sorter'
