Hi,
if you want the project to investigate this, it would be useful if you
provide a sample program that exhibits this behaviour with a vanilla
build of 2.4.48 and doesn't exhibit that with an analogous build of
2.4.23.

I would like to point out that since 2.4.23 is a very old release, it is
also possible you have been relying on undocumented behaviour or a
libldap_r bug that has since been fixed. That is what a sample program
would also help to rule out.

Regards,
