Reggie Perry pointed out a serious bug in unexalpha.c that got introduced a few betas ago -- a call to bcopy got converted to memcpy without the parameters being reversed. The following patch is in b42 (which will be released shortly). 1998-06-01 SL Baur <steve(a)altair.xemacs.org&gt; * unexalpha.c (unexec): Reverse parameters in call to memcpy.
