GMC adds this itself.  If you remove the entire ~/desktop directory, not just 
the link, running gmc recreates it again, and then cores again ;O)  As you say, 
removing just the link solves it.

I then had it SEGV in turn on a series of other files, seemingly all of which 
had non-alpha characters in them (eg .!dtmarkbo, .@desktop, .Bugtraqrc, etc) in  
re_match_2_internal:

0  0x6f3fc in re_match_2_internal (bufp=0xffbee810, string1=0x0, size1=0, 
    string2=0x182210 ".Bugtraqrc", size2=10, pos=0, regs=0x0, stop=10)
    at regex.c:3679

Which is:

   /* Initialize subexpression text positions to -1 to mark ones that no
      start_memory/stop_memory has been seen for. Also initialize the
      register information struct.  */
   for (mcnt = 1; mcnt < num_regs; mcnt++)
     {
>      regstart[mcnt] = regend[mcnt] 
         = old_regstart[mcnt] = old_regend[mcnt] = REG_UNSET_VALUE;
        
And if this works for some files, and not others, I'm somewhat at a loss to why 
=O(

I worked my way through removing each of these files in turn for a while until I 
got bored of doing it.  It didn't spit on all of my ~/.??* files - just some of 
them.  I didn't get far enough to see if it SEGVs on files not starting with a 
".".  Most confusing.

Hope this is useful to someone,
