vm-visit-folder GC crash still occurring

Hello, Back in September I submitted the following bug report: http://list-archive.xemacs.org/xemacs-beta/200109/msg00357.html [Brief summary: uname -a: CYGWIN_NT-4.0 PASTON 1.3.3(0.46/3/2) 2001-09-12 23:54 i686 unknown ./configure '--with-dragndrop' '--site-includes=/usr/include/w32api' XEmacs 21.5-b3 "asparagus" configured for `i686-pc-cygwin'. M-x vm-visit-folder Visit folder: <large (22M) folder with about 5000 messages> xemacs exits with no messages or stack. Repeatably. This didn't occur with a 21.5-b2 (ish) build.] AFAIK, no one followed this up at the time. I've tried a few more combinations. I can repeat the bug with: the latest 21.4 and 21.4-b4 on cygwin/W2K 21.5-b2 on cygwin/W2K But not with 21.5-b4 on my i686-pc-linux 21.5-b0 on cygwin/NT Unfortunately the two mail files that tickle this bug contain company sensitive information. I've made "clean" VM files of a similar size, but these don't cause the crash - probably because they don't contain complex MIME messages and hence don't cause so much garbage when parsed. Can anyone comment on the stack trace provided with the original report? Maybe someone can guess what happened between 21.5-b1 and 21.5b2 to cause this? Thanks, - Phil
