If you use the nroff line-drawing function to underline, you can get what you
want.  Use the following macro, taken verbatim from Ossanna's 'NROFF/TROFF
User's Manual, section 12.4:

	.de us
	\\$1\l'|0\(ul'
	..

The command .us "coredumpsize" will then produce what you want.

Note that this is the only way to underline anything in troff.
