Dear XRootD devs,

We upgraded our XRootD servers/redirectors to version v5.4.3-1 and it seems that the adler32 checksum is not working anymore, e.g.: 

#### No adler32 output
$ gfal-sum root://xxxx:1094/xrootd/in2p3.fr/disk/dteam/testNagios.root adler32
root://xxxxx:1094/xrootd/in2p3.fr/disk/dteam/testNagios.root

In the XRootD server log file :

220627 22:07:16 1000359 XrootdXeq: xxxxxx.16533:29@[xxx.yyy.zzz.ttt] pub IP64 login as 2162d177.0
/usr/bin/xrdadler32: symbol lookup error: /lib64/libXrdCl.so.3: undefined symbol: _ZdlPvm
220627 22:07:16 1000359 XrootdXeq: xxxxxx.16533:29@[xxx.yyy.zzz.ttt] disc 0:00:04


So it seems that something is broken in the library libXrdCl, with:

$ rpm -qf /usr/bin/xrdadler32
xrootd-client-5.4.3-1.el7.x86_64

$ rpm -qf /lib64/libXrdCl.so.3
xrootd-client-libs-5.4.3-1.el7.x86_64
