Error Compiling LibreOffice Core on Debian 12 - x64

[Andreas Mantke <maand@xxxxxx>]

Hello,

I try to compile LibreOffice core on Debian 12 -x64 but the process
ended with an error.

Here the messages in the shell at the end of the build process:

[MOD] unoxml

I tried in parallel with a build on openSUSE 15.5 -x64 and the build of
LibreOffice  core was successful.

Any hints about a workaround or fix?

Regards,
Andreas
