Right. It has probably to do with some linking and initialization
details of the dynamic libraries involved. However, in my case the
offending interaction seemed to be just between the PHP extension
modules. To fix the problem I didn't have to change the load order of
the Apache modules.
Since then I have a line in my PHP upgrade notes that reminds me of
sorting the extension list as a last step. This is certainly a
pragmatic approach, but for lack of time I didn't bother getting
acquainted with the PHP internals, and those of the libs involved, to
find the root cause.
