This month I finally managed to get a usable installation of eComStation   
   running under VirtualBox in Linux. It's amazing how many old installers want   
   to modify CONFIG.SYS which causes OS/2 to become unbootable due to system DLL   
   version mismatches, etc.   
      
   The VirtualBox Additions work well, so I can copy & paste between Linux and   
   OS/2 using the shared clipboard. Very cool. Also I finally worked out how to   
   connect OS/2 to a Samba share.   
      
   Anyway, I've ported MakeNL to IBM VisualAge for OS/2 and in the process   
   managed to code a workaround for the crash in the Watcom OS/2 version. See the   
   recent CVS commits. I suspect I've just hidden the problem though.   
      
   Probably related, I'm seeing segfaults with the EMX version:

   Clearly another part of the code is corrupting MessageDir.   
      
   I saw this bug in the Turbo C (DOS) version too a few weeks back, but there's   
   obviously no memory protection there, so I wasn't sure how to begin to debug   
   it.   
      
   Anyway, progress. :-)
