i finally migrated the LOGON tree to using Allegro CL 10.0 (from 8.2,<br>
for the past many years). in principle, there should be no visible<br>
changes to users of the run-time images.<br>
<br>
but it appears the new compiler (using the LOGON compiler setting)<br>
generates faster and less robust code: i have already analyzed one<br>
previously unnoticed bug, where calling subseq() with a negative start<br>
index apparently used to quietly return an empty sequence but now<br>
(correctly) raises an exception.<br>
<br>
in other words, there may after all be unexpected behavior, most<br>
likely from exposing ‘sleeper’ bugs. hence, please ‘make update’ your<br>
LOGON tree (or just get a fresh installation), watch out for suprising<br>
behavor, and let me (and the LOGON list) know your findings!<br>
<br>
except for dan, i am not aware of LOGON users running from sources<br>
nowadays. if you do, once you ‘svn up’ below the optional add-on<br>
‘franz/linux.x86.64/’ you will need a fresh ‘devel.lic’ license file<br>
for Allegro CL version 10.0.<br>
<br>
—part of my motivation for taking this move have been recurrent fatal<br>
errors (SEGV) over the past several months in the ERG on-line<br>
demonstrator, which have put a few dents in our previously stellar<br>
uptime record. i optimistically hope that these errors will be gone<br>
now! come to think of it, they might actually be related to the<br>
subseq() bug mentioned above ...<br>
<br>
best wishes, oe<br>
