Almost certainly you're wrong.  The key is that [a-z] is not really a
valid "alpharacter interval" any more, as soon as locales other than
"C" or "POSIX" are involved.

The fact that to demonstrate this error you had to change not just
gawk versions, but also the entire Linux distribution it ran on,
should have warned you that other influences might be at play here.
You changed at least two major tools, and the result was different.
That's no way to deduce that one of the tools was the culprit.
