 void pdf_print::file_xref()
      ^~~~~~~~~
pdf_print.cc:1238:13: note: ‘sprintf’ output between 21 and 28 bytes into a destination of size 20
     sprintf (tstring, "%010d %05d %c \n", u->byte_offset, u->generation, u->use);
     ~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Hi - Can you send me a tab file that causes this issue? Would it be better to increasae the buffer than write a warning? Wayne

No not using PDF output, this is just a compiler warning. The program runs fine on the included samples.
