From what I understand the change has been triggered by the move of the pthread_exit() function from libpthread.so.1 to libc.so.6, which happened in glibc 2.34. libgcc_s.so.1 is loaded dynamically when such function is used to avoid a dependency loop, so libc.so.6 is NOT linked against libgcc_s.so.1. This is not something new, it has been like that for 10+ years. > bug? I.e. is one of glibc's binaries missing a dependency? Technically the libc6 package is indeed missing a dependency against libgcc-s1. This is not an issue given libgcc-s1 is de facto essential. On the glibc side, it should be possible to add such a dependency (although it would not have prevented this bug), but that will create a dependency loop, and tools (apt, aptitude, rebootstrap, ...) would have to learn how to deal with it.
