SY> Could you try to get a backtrace and send in a bug report SY> (probably be a good idea to Cc Ben Wing <ben(a)xemacs.org>). This is the best I can do. The backtrace was really huge (infinite!?) so I had to truncate it. The loop is visible below. Note that this occurs only after a make distclean. Making again doesn't trigger the bug (and the file is compiled next time. Possibly after a make -k.) It is time consuming business so I haven't tried all variants of this. Core was generated by `xemacs -no-autoloads -batch -debug-init -l /usr/local/src/packages/package-comp'.
