I figured out the problem with saving aliases crashing the mud with
circle30bpl14.  This pertains to using the alias patch from the circle ftp
site.

This was the call that was crashing the mud when I would save the alias

get_filename(GET_NAME(ch), pcFileName, ALIAS_FILE);  <-- From alias.c

In get_filename (utils.c)

const char *prefix, *middle, *suffix;
  char name[64], *ptr;

  switch (mode) {
  case CRASH_FILE:
    prefix = LIB_PLROBJS;
    suffix = SUF_OBJS;
    break;
  case ETEXT_FILE:
    prefix = LIB_PLRTEXT;
    suffix = SUF_TEXT;
    break;
  case ALIAS_FILE:
        prefix = "PLRALIAS"; <====== This should be - prefix="PLRALIAS/"
        suffix = "alias";
        break;

One little slash was the culprit.  I didn't catch this because the other 2
cases Crash_file and Etext_file are defined in db.h.  It was there that I
found the the directories must have slashes.  This obviously wasn't the case
in earlier versions of circle.

Thanks to all who helped me get to the bottom of this.
