/usr/local/bin/ssphys: unrecognized file during LOADVSSNAMES

[Marcel Juffermans]

OK, so I've compiled again with -g flag, and run it through gdb. The  
problem occurs in eType SSRecord::GetType () because m_pBuffer is  
null. I found the other private data defined in SSRecord.h and  
printed them:

(gdb) print m_Header
$8 = {
   size = 0,
   type = "\000",
   checksum = 0
}
(gdb) print m_pBuffer
$9 = (byte *) 0x0
(gdb) print m_FileImpPtr
$10 = {
   px = 0xd01390,
   pn = {
     pi_ = 0xd013b0
   }
}
(gdb) print m_Header
$11 = {
   size = 0,
   type = "\000",
   checksum = 0
}
(gdb) print m_pBuffer
$12 = (byte *) 0x0
(gdb) print m_Len
$13 = 0
(gdb) print m_Offset
$14 = 52
(gdb) print m_FileImpPtr
$15 = {
   px = 0xd01390,
   pn = {
     pi_ = 0xd013b0
   }
}

Good fun, I've never done this before! Can't see straight away why  
this happens, though. Any ideas?

Thanks,

- Marcel
