I have been holding version 261~rc1-1 to keep programs using libopenal 
working, but have now found time to bisect the problem.  After cloning 
the Debian systemd git repository from

     https://salsa.debian.org/systemd-team/systemd.git

and on branch "debian/master" located tags corresponding to the last 
version for which libopenal was unaffected,

     debian/261_rc1-1

and the first version which prevents libopenal from working,

     debian/261_rc2-1

Using 'git bisect' with these tags specifying "good" and "bad" versions, 
I was able to identify this commit as the first causing the problem with 
libopenal:

a05fe6684ae0af8128c20e2054d52d8393c2ac61 is the first bad commit

     libc: dlsym the time64 alias for epoll_pwait2() on 32-bit _TIME_BITS=64


Afterwords, I attempted a couple of simple reverts successfully.  First, 
I created a branch off tag "debian/261_rc2-1" and ran 'git revert 
a05fe6684a'; this succeeded, and the packages I built no longer broke 
programs using libopenal.  Second, I created a branch off tag 
"debian/261.1-3" and successfully carried out the same revert; the 
package built, and libopenal worked correctly now.


HTH,
