openjade crashes while compiling pgpool docs

[Tatsuo Ishii]

VERSION="20.04.2 LTS (Focal Fossa)"
openjade: 1.4devel1-21.3ubuntu1

While compiling Pgpool-II (https://pgpool.net) SGML documents, openjade crashes.

t-ishii$ LANG=C make
/usr/bin/mkdir -p html
openjade -wall -wno-unused-param -wno-empty -wfully-tagged -c /usr/share/sgml/docbook/stylesheet/dsssl/modular/catalog -d stylesheet.dsl -t sgml -i output-html -V html-index pgpool.sgml
make: *** [Makefile:528: HTML.index] Segmentation fault (core dumped)

This happens on current Pgpool-II master branch or other stable releases. Also please note that openjade works fine on Ubuntu 18 and CentOS 7, 8.

Here is a backtrace:

(gdb) run -wall -wno-unused-param -wno-empty -wfully-tagged -c /usr/share/sgml/docbook/stylesheet/dsssl/modular/catalog -d stylesheet.dsl -t sgml -i output-html -V html-index pgpool.sgml
