Hello
Below is a forwarded email from Remi (awaits moderator approval for
xrootd-l).

I have an ugly problem with xrdcp from today's cvs HEAD when it tries
to create more than one new directory on the server. It crashes in
XrdClientConn::ReadPartialAnswer after creation of the 2nd or higher
directory. Interestingly, sometimes it succeeds.
This worked flawlessly with the cvs version from Nov 12.
I tried bbrprod01 and bbrprod05 with the same result.
Here the output from gdb:
(gdb) run -d2 KanAccess.cfg
root://bbrprod05:1094////prod/subskim/SPskims/test5/001237/200301/1008/
S0002/V04/
The program being debugged has been started already.
Start it from the beginning? (y or n) y
