The best solution would be to fix the X server. Try and see whether redhat has an update. Jan

XEmacs' GC is not exactly fast as it is. > Making it any slower would be a mistake. It depends. If (most) objects XEmacs are organised in pools it would be possible to write the sweep loop such that it is scans over the heap in a linear fashion, backtracking only occasionally. Supposing the locality of reference is good an the hashing is done per page that means that the hash is needed relatively seldom. In addition in such an implementation the _address_ is used in the hash table. The object itself is not needed until the sweep arrives. My guess would be that this would produce better cache behaviour that would offset any computational disadvantages. I think it is time to save a copy of XEmacs for benchmark comparisons. Jan

Xemacs crashes my linux! 24 years, 7 months

morten.stenseth＠baerum-kommune.telemax.no

Hi, I have had som problems with xemacs 21.2.15 to 21.2.19, everytime i start up xemacs,it crashes linux when the xemacs-beta logo becomes visible, but the problem only happens when the xemacs welcome screen becomes visible , if i f.ex types xemacs ~/.emacs the problem does not occur. Anyone have a solution to this problem? Thanks. Morten Stenseth <morste(a)baerum-kommune.telemax.no> ( btw: i am running Xemacs 21.2.19,redhat 6.0 with a 2.2.5 kernel )

Well, the bytecode stack seems to be corrupted. Could some call to the LDAP lib have caused this? On the other hand a dialog box seems to be involved in Raymond's recipe, so it could also be related to motif or something. Raymond, could you look a bit closer at this, e.g. check when & where the stack is corrupted? dbx on Solaris has these fantastic watchpoints which might be helpful for this. Gunnar

Press No. Raymond> Crash! According to the Lisp and C backtraces and the description you give, the problem is certainly not in your LDAP libraries: there's no call to the LDAP routines involved in what you describe. So I don't think UMich libs will help in any way. The problem seems to be rather related to Custom instead. Something might be wrong in the definition of ldap-host-parameters-alist but that should never trigger a crash anyway. Oscar
