glib2-2.79.0-2.fc40 added g_once_init_enter_pointer symbol and started to implant a reference on the symbol into applications via macros/in-lined functions included from glib2 header files. As a result, people upgrading to libdnf built against new glib2 but not upgrading glib2 at the same time will break dynamic linking of libdnf:
If glib2 versioned its symbols, rpm-build would inject an RPM dependency on the new glib2 versioned SONAME. However, this is not true, so we need to add a dependency on a minimal glib2 version manually.
This issue is specific to not fully upgraded Fedora 40--41. This issue materializes in real life when mock installs a new libdnf into a bootstrap image based on a container image created before glib2-2.79.0-2.fc40
