Description of problem: malloc hooks and debugging support have been moved from libc.so to a new DSO libc_malloc_debug.so, which can be preloaded to get the functionality back. The DSO will get installed by default into glibc but it should be in glibc-devel or glibc-utils to allow its removal from the core library. Indicative PR here: https://src.fedoraproject.org/rpms/glibc/pull-request/35
Latest minimal change that needs review: https://src.fedoraproject.org/rpms/glibc/pull-request/37# Florian needs to review this change.
The plan here is to make this change after August 12th. We have various other tasks that are competing for resources. There is no risk in waiting except that we need to make changes in F35 and Rawhide.
This bug appears to have been reported against 'rawhide' during the Fedora 35 development cycle. Changing version to 35.
libc_malloc_debug.so has been dropped and symbols in libc_malloc_debug.so.0 are no longer available as dependencies. libc_malloc_debug.so.0 is still in the main glibc package for now as we couldn't agree on moving it to a separate package. Builds are in progress.
