Hi all: The new glib 2.34 release has a major and welcome change.
* In order to support smoother in-place-upgrades and to simplify the implementation of the runtime all functionality formerly implemented in the libraries libpthread, libdl, libutil, libanl has been integrated into libc. New applications do not need to link with -lpthread -ldl -lutil -lanl anymore. For backwards compatibility, empty static archives libpthread.a libdl.a libutil.a libanl.a are provided, so that the linker options keep working. Applications which have been linked against glibc 2.33 or earlier continue to load the corresponding shared objects (which are now empty). The integration of those libraries into libc means that additional symbols become available by default. This can cause applications that contain weak references to take unexpected code paths that would only have been used in previous glibc versions when e.g. preloading libpthread.so.0, potentially exposing application bugs. Attribution Carlos' email https://sourceware.org/pipermail/libc-alpha/2021-August/129718.html warm regards Saifi.
