Compilation of documentation in drbd-util-9.31.0 dumps core

Hi all,

just trying to compile drbd-util-9.31.0 on Alma Linux 9.5 all updates installed.
When the makefile is trying to build the documentation I get a sigsegv while /usr/bin/xsltproc is called:

/usr/bin/xsltproc \
--xinclude --stringparam variablelist.term.break.after 1 \
http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl drbdsetup.xml
realloc failed !
make[1]: *** [../../documentation/common/Makefile_v9_com_post:46: drbdsetup.8] Segmentation fault (core dumped)
make[1]: Leaving directory '/opt/data/install/drbd/drbd-utils-9.31.0/documentation/v9'

Version of xsltproc is 1.1.34. With version 9.30.0 I had no problems generating the documentation. also locally installed are the following packages:
docbook-style-xsl help2man libxslt libxslt-devel linuxdoc-tools po4a

Can anybody probably give a hint to resolve this problem?

Best regards
Andreas
