[Help-bash] xtrace ordering problem

[B Hope]

Hello,

Apologies if you get this e-mail twice.

I am using "set -x" to debug a shell script. On a single core VM I get the debug output (the lines beginning "+ ") reversed. The script ends with the same result. Should the order of the output when using "-x" always be the same?

$ cat b.sh
#!/bin/bash
/usr/bin/tail -n 100 messages | /bin/grep blah | md5sum

$ bash -x b.sh
+ md5sum
+ /usr/bin/grep blah
+ /usr/bin/tail -n 100 messages
