           Summary: 1.15.2 regression from 1.15.1 in ash parameter expansion
           Product: Busybox
           Version: 1.15.x
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
        AssignedTo: unassigned at busybox.net
        ReportedBy: davide at geexbox.org
                CC: busybox-cvs at busybox.net
   Estimated Hours: 0.0


What happens:
$ ./busybox ash

BusyBox v1.15.2 (2009-11-25 04:37:07 CET) built-in shell (ash)
Enter 'help' for a list of built-in commands.

$ arg='boot=cdrom'
$ echo $arg
boot=cdrom
$ BOOT="${arg#boot=}"
(locks forever...)
^C
$ 

1.15.1 didn't have this problem. Applying this patch to 1.15.2
http://hg.geexbox.org/geexbox?cmd=changeset;node=78663e485688
fixes the problem, so the code responsible for the regression is someplace in
there.

Regards,
Davide
