           Summary: Phantasmagoria 1 crashes at startup
           Product: Wine
           Version: 1.1.6
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: dos
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: deadlock at start.no


When I run Phantasmagoria 1, it will crash right after calling int 31, ax=0001
which is a DPMI interrupt, free LDT descriptor. Which means that it crashes
somewhere around line 882 in file dlls/winedos/int31.c I then commented out
what's between the else { and }. The comment that is already there reads:
  /* If a segment register contains the selector being freed, */
  /* set it to zero. */

Which probably means that the game tries to use either the DS, ES, FS or GS
segment after it has freed the LDT descriptor. Is this function/interrupt
really supposed to fiddle with DS, ES, FS and GS? I can't see any mention of
that in the DPMI
specifications(http://www.delorie.com/djgpp/doc/dpmi/api/310001.html) and
apparently Windows handles it differently, since it won't crash when I comment
out the lines that reset these segments.
