Dear All,

I am seeing AOO 4.1.16-RC3 crash on openSUSE due to an issue with libexpat.

Stack trace (I have debug symbols installed for fontconfig):

Note that libexpat.so.1 is in /usr/lib64, i.e. it is the ``system''
version, delivered by openSUSE.

I could fix the issue on my own AOO41X builds by adding parameter
--with-system-expat to the configure script.  See commit
8ab1c45d01e8d22fb3a8e12992ebfcb53306f3c2 to the openoffice-devtools
repository.

I think that the above parameter is not given to the RC binaries?
Jim, could you please confirm?

You can find the build parameters here:

https://github.com/apache/openoffice-devtools/tree/main/build-scripts/4.1.16

Are we building our own version of libexpat in the official builds? If
so, then we shall also ship it in binary form... shall we not?

I apologize for not having reported this on former RC builds.

Thank you in advance and best regards,
