My concern is how that is acting differently on AIX.

That is exactly my point. You are in the enviable position of having the debugger's holy grail:

Repeatable scenarios that differentiate exactly on the bug description.

But, rather than exploiting that perfect tool, you appear to want to debug by crowd-sourced guessing....

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
