Package: w3m
Version: 0.5.1-4
Followup-For: Bug #372171
w3m segfaults (about 70% of the time, based on my informal testing) when
searching either forward (/) or in reverse (?). Like the previous reporter,
I'm marking this one grave for the same reasons: it's my primary means of
navigation within long pages, and I believe that this is true for most
users as well.
Relevant part of an strace dump (I'm opening a file, "foo.html", that has
no content beyond the basic HTML structure):
