This appears to be fixed in git head. Could you try git head? What version were you using?

[jmuf]

I was using the 3.3.2 client rpm as released by Lukasz last week. Sorry, cannot try out things for the next few days (absent).
Cheers

OK, this problem is indeed fixed in git head. It seems the patch was not marked critical because it included another less critical patch. So, indeed 3.3.2 is broken w.r.t. to xrdcp and envar setting (plus a couple of other end cases which you haven't encountered yet). I don't know if we have a 3.3.3 on schedule. I will ask Lukasz.

Yes, it's my fault, I missed the fix 49b23a9 when preparing 3.3.2.

Ported to stable-3.3.x
