The strace output is showing that the correct 'touch' is being executed.

Notice that the child process pid=6747 exits with status 0, but $?=1
after returning from executing touch. This triggers the failure.
I just upgrade my bash from version 3.21 to 4.2 and I'm still seeing
this problem.
I am seeing this failure whether I execute the 'touch' command or the
'stat' command. Both of these are incidentally busybox
implementations.
ls -al /bin/touch
lrwxrwxrwx 1 root root 7 Nov 15 08:07 /bin/touch -> busybox
ls -al /bin/stat
lrwxrwxrwx 1 root root 7 Nov 15 08:07 /bin/stat -> busybox
Are there any bash debugging tools available that I can use to halt on
a data breakpoint and examine state?
Thanks,
Dallas
