I've tried to narrow it down further, but I haven't found a better testcase. This is essentially what I have set up on my server, and it works with the 2.2 patches, but not the 2.4 patches. So clearly there's a regression here, but I'm not sure what exactly triggers the problem. > I installed Apache and mpm-itk, enabled the cgi module, set AssignUserID > to “sesse www-data” (sesse is not normally a member of www-data).

What I think might be happening is that the first one, which runs as www-data:www-data, is somehow causing problems for the second one, which runs as bmc:www-data. That's all I have to go on. I can say that I still have the problem if I force the info/refs call to be bmc:www-data as well by placing the AssignUserID statement into the <LocationMatch "^/git/"> block. However, if I place it outside of the block, in the main VirtualHost, it works just fine.
