Bug in glibc 2.39

Hi, Since the 20240202 TW snapshot, glibc 2.38 was replaced with 2.39. Since then, USB passthrou for VirtualBox has failed. This was verified by reinstalling 2.38 from the Slowroll repos to a fully updated TW system. None of the listed changes leap out as a probable cause, but I hope that this will jog the memory of one or more of the devs. The bug report is at boo#1219766. Thanks, Larry
