Follow-up Comment #4:


commit 57fac864952a671593647ae85751feb3a54971fd

    [grohtml]: Fix Savannah #61748.
    
    * src/devices/grohtml/post-html.cpp (style::style): Add initializer to
      argumentless constructor to avoid later read from unitialized memory
      in `html_printer::do_font`.
    
    Fixes <https://savannah.gnu.org/bugs/?61748>.

commit 525fe85ec9de643999e44a77568d66a7913b77b1
Author: G. Branden Robinson <g.branden.robinson@gmail.com>

    [groff]: Add regression test for Savannah #61748.
    
    * src/roff/groff/tests/html_works_with_grn_and_eqn.sh: Do it.
    * src/roff/groff/groff.am (groff_TESTS): Run it.
    
    Test may loop infinitely at this commit; since the behavior depends on
    a read from uninitialized memory, I doubt that it is deterministic
    across system configurations.
