           Summary: awk parsing bug
           Product: Busybox
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: Other
        AssignedTo: unassigned at busybox.net
        ReportedBy: charles.fisher at alcoa.com

   Estimated Hours: 0.0


The following runs successfully with gawk:

     BEGIN { print "Enter some stuff, stop with . (dot):\n"

     while(getline) if($1 == "." && NF == 1) break; else list[i++] = $0

     for(j=0; j<i; j++) print list[j] }

It fails in busybox with:

     $ /sbin/busybox awk -f testcase.awk
     awk: testcase.awk:3: Unexpected token

If I adjust the script to the following, it will run properly:

     BEGIN { print "Enter some stuff, stop with . (dot):\n"

     while(getline) if($1 == "." && NF == 1)
             { break }
     else list[i++] = $0

     for(j=0; j<i; j++) print list[j] }

I have found this behavior on Oracle Linux 5.10 Busybox version 1.2.0, and
Mingw-Win32 Busybox version v1.23.0-TIG-1525-ge19594c
