Unfortunately, I cannot duplicate your results on Pentium Linux.

xemacs -q
C-x C-f man/gnus.texi
M-: (re-search-forward "\\(.\\|\n\\)*")

XEmacs 20.1-b1/MULE:	Stack overflow in regexp matcher
XEmacs 20.1-b1/latin-1:	Stack overflow in regexp matcher
XEmacs 20.0/MULE:	Stack overflow in regexp matcher
XEmacs 19.15:		Stack overflow in regexp matcher
XEmacs 19.14:		zsh: 22093 segmentation fault  xemacs-19.14 -q
