New restrictions on shared memory break awgtpman

Bram Slagmolen writes

I get a segmentation fault in awgtpman. I apt update with yesterdays version (rtcds --version -> 5.0.0~deb11202203212205), and after I compile and install my iop, I check with rtcds status n1iopfe0, the awgtpman service has failed. When trying to start manually awgtpman -s n1iopfe0 it gives a segmentation fault. Any suggestions on how to check?
