Hmmm... I'm looking at the code that you said was causing the assert in
version 0.16.1.   This is what I see (in tn5250_wtd_context_write_field,
around line #360):

      /* Put the field control word(s). */
      if (field->FCW != 0) {
         tn5250_wtd_context_putc (This, (unsigned char)(field->FCW >> 8));
         tn5250_wtd_context_putc (This, (unsigned char)(field->FCW & 0x00ff));
      }
   }  

   /* Put the screen attribute. */
   /* FIXME: Re-enable assert: TN5250_ASSERT (tn5250_attribute (attr)); */
   tn5250_wtd_context_putc (This, attr);


You'll note that the assert that's failing is commented out.   How could
that assertion fail if the assert is commented out?!

Does your copy of 0.16.1 have that assert commented out?  Maybe we're not
looking at the same code...

tn5250 trace=/path/to/somefile.txt . . .

Beware!  The tracefile will contain everything that happens in your tn5250
session, and therefore will contain your password.  I'd recommend creating
a "test" account to reproduce the problem with, create the tracefile,
then delete the test account.

I can do that, but without knowing how to reproduce the problem, it 
wouldn't help. :)
