(dbx) p tgath_buf[curr_len - 1]
tgath_buf[curr_len-1] = '\0'
(dbx) p buf[curr_len-1]
dbx: cannot access address 0x9f7f6ff
(dbx) p tgath_buf[curr_len - 2]
tgath_buf[curr_len-2] = '\0'
(dbx) p buf[curr_len-2]
dbx: cannot access address 0x9f7f6fe
(dbx)

Something is definitely wrong with this memcpy() operation. I 
suppose we'll need some help from the HDF5 folks to figure out 
what the buf memory buffer is supposed contain in this case.

After the macro expansion, this code looks like this:

         for(curr_seq=0; curr_seq<nseq; curr_seq++) {
             curr_len=len[curr_seq];
              memcpy ( ( char * ) ( tgath_buf ) , ( const char * 
) ( buf + off [curr_seq ] ) , curr_len );
             tgath_buf+=curr_len;
         }

No. We can try that, as well as lint.

Thanks.
