To check troff/groff input files for errors, run:

groff -b -z -w w filename

EXAMPLE:

groff -b -z -w w /usr/share/man/cat1/f77.0

/usr/share/man/cat1/f77.0:421: warning: escape character ignored before a backspace character
/usr/share/man/cat1/f77.0:425: warning: escape character ignored before a backspace character
/usr/share/man/cat1/f77.0:425: a backspace character is not allowed in an escape name
