Okay,
the mud breaked at do_oasis:

Breakpoint 1, do_oasis (ch=0x82e2e88, argument=0xbffff871 "", cmd=205
    subcmd=0) at oasis.c:74

(oasis.c:74 is first line in function)

print d gives:
$1 = (struct descriptor_data *) 0x1004

print ch->desc gives:
2 = (struct descriptor_data *) 0x0

print ch gives:
$3 = (struct char_data *) 0x82e2e88

---------------------------------------------------------
From the core file:

Segmentation fault.

#0 do_oasis (ch=0x82e2ea8, argument=0xbffff881 "", cmd=205, subcmd=0)
   at oasis.c:148

print d gives:
$1 = (struct descriptor_data *) 0x0

print ch-desc gives:
$2 = (struct descriptor_data *) 0x0

print ch gives:
$3 = (struct char_data *) 0x82e2ea8
------------------------------------------------------------------

at oasis.c:148

  /*
   * Give descriptor an OLC structure.
   */
  if (d->olc) {               <------------ this is line 148
    mudlog("SYSERR: do_oasis: Player already had olc structure.", BRF,
LVL_IMMORT, TRUE);
    free(d->olc);
  }
  CREATE(d->olc, struct oasis_olc_data, 1);
---------------------------------------------------------------


shrug....
