Hmm. Perhaps this is the nature of the linker change in 2.3? My understanding, at least from reading the GNU info docs, is that preference is given to libraries that the calling object is directly linked against IFF -Bsymbolic was used. If the ELF standard permits the runtime linker to do this when -Bsymbolic was /not/ used, then it's cleary a bug for the PHP DSO to depend on the 2.2 behavior. -- Steve Langasek postmodern programmer
