I cannot reliably reproduce it at all, it just happens after
a, usually very long (as in, days) time of browsing cookie-
happy sites (fanfiction sites, in this case, mostly).

Right, but that's only the place where it segfaulted, not
necessarily the place where the bug occurs (as I wrote, I
suspect a faulty but non-NULL entry in the list somewhere,
possibly a use-after-free, possibly a corruption).

Hrm.
Of course I cannot reliably say it was introduced in dev.15,
just that it started to happen to me lately – maybe some site
redesign (fanfiction.net did one, AO3 maybe too) is the actual
cause.
Sorry for that.
I can do a debug build and save the core file next time, if
you want. (Would be useful if the signal handler can be dis-
abled, is there a compile-time option for that? Otherwise,
gdb cannot inspect the stack frames beyond the handler.)
