Description of problem:
ksh crashes due to assertion failure


Version-Release number of selected component (if applicable):
2020.0.0

How reproducible: Always


Steps to Reproduce:
Run the following shell function:
function pigs
{
        print - "Pid\tBytes\t\t\tTime\t\tProgram"
        print - "===\t=====\t\t\t====\t\t======="
        ps -efal | tail -n +2 | sort -r -n -k 10,10 | head -20 | awk -v pagesize=`pagesize` '\
        BEGIN { size = 0; }
        {
                n = split($14, array, ":");
                if (n > 1) {
                        time = $14
                        prog = $15;
                } else {
                        time = $15
                        prog = $16;
                }
                size = $10 * pagesize;
                printf("%d\t%s\t\t%s\t%s\n", $4, size, time, prog);
        } '
}

Actual results:
../src/cmd/ksh93/sh/jobs.c:1110: failed assertion 'pw'
/bin/ksh: pigs: line 181: 6774: Abort(coredump)


Expected results:
function runs without causing shell to crash.
