Description:
I tried to build libreoffice 7.5.4 with gcc 12.3.0 on riscv64 but it failed:

/usr/bin/ld: /home/infinity/libreoffice-build/workdir/CxxObject/xmloff/source/core/xmlimp.o: in function `.LEHB218':                                                                                
xmlimp.cxx:(.text+0x6256): undefined reference to `non-virtual thunk to cppu::WeakImplHelper<com::
sun::star::xml::sax::XFastAttributeList, com::sun::star::util::XCloneable>::acquire()'
collect2: error: ld returned 1 exit status
make[1]: *** [/home/infinity/libreoffice-build/xmloff/Library_xo.mk:20: /home/infinity/libreoffice
-build/instdir/program/libxolo.so] Error 1
make: *** [Makefile:289: build] Error 2

The error log is almost same with bug 142442[1] and bug 145656[2].

Although in bug 142442 gcc-10 patch[3] was mentioned, but it seems that the patch solved another problem[4] about 'XSeekable', which is different to 'XCloneable'. I have applied the patch, it does not help with this error.

I tried to modify 'xmloff/source/core/xmlimp.cxx' but it doesn't work:

+template class css::uno::Reference < css::util::XCloneable >;
