[mdb-dev] There are always problems to work whith JET3

[Emilio P. <ep....@ce...>]

I try since few days to work on databases in JET3 format. The result is always 
a segmentation fault; it seems to work only the db-ver utility.

I saw the mail from Gordon MacQueen and the answare by Jeff Smith on 
3-11-2005; and hoped there was the solution, but it seems no.

Debugging the sources I find that the problem arises in the function 
mdb_read_row: here the call to mdb_find_row(mdb, row, &row_start, &row_size) 
puts a negative value into row_size at the end of the database.

I jump over the problem modifying data.c as follows
  
 ..........
   255                  lookupflag ? "[lookup]" : "",
   256                  delflag ? "[delflag]" : "");
   257  #endif
   258          /** Patch by Cesip */     
   259          if ( row_size < 0 )
   260                  return 0;
   261          /** End patch **/
................

Is this solution valid in every case ? or does exist a better generalized 
one ?

Thank you for attention.
