[Antelope] trace table record length

[Dr. Kent Lindquist]

Hello Phil,

Are you using the same version of Antelope for both tests? I believe  
the length of the Dbptr field type in the Trace4.0 schema changed from  
16 to 32 characters between Antelope 4.9 and 4.10.

Best regards
Kent

% diff /opt/antelope/4.9/data/schemas/Trace4.0 /opt/antelope/4.10/data/ 
schemas/Trace4.0 | grep Dbptr
<       Dbptr (16)
 >       Dbptr (32)
<       Dbptr (16)
 >       Dbptr (32)
<       Dbptr (16)
 >       Dbptr (32)
<       Dbptr (16)
 >       Dbptr (32)
