I've played with it a bit, but it never struck me as being so cool to
warrant a move to it quite yet.

In general, segfaults could also happen because of mismatched libmysqlclient
versions and architectures (compiled for i386 or x86_64, for example).
Something that is always tricky (not only when compiling against
libmysqlclient) is getting PHP to link against the right libs (look at
--with-libdir=lib64 which is something I requested some time ago).

I've also reported this bug recently:

I'm currently using SoapClient, and although improved, it's still a little
shaky.

Ironically enough, NYPHP was recently approached by this group:

http://wso2.org/

and specifically:

http://wso2.org/projects/wsf/php

It's built on some solid XML/SOAP technology, and from messing with it a
little bit, looks very promising.  I'm actually discussing some issues with
their developers, surrounding complex WSDLs (which always seem to be a
problem).  They're releasing a new version this week, and from what they've
shown to me by using some test WSDLs, it's going to be solid.  And it
includes automatic class generation from the WSDL, which is the way SOAP is
supposed to be - finally in PHP!

I hear you - a real time killer, so generally I don't have the chance to
research... gone are those days...
