Digital UNIX and regex.c with REGEX_MALLOC defined.

Last week I asked about XEmacs-21.4.0 crashing on Digital Unix and Gunnar Evermann pointed out that this problem is already reported in PROBLEMS file. As Stephen just told that bug reports should be preferably sent to xemacs-beta list, below is copy of article sent to comp.emacs.xemacs few days ago. And my question is that should the REGEX_MALLOC definition work?
