Re: [Nano-devel] updates, 1.3.9pre1 soon (Debian bug #325065)

[David Lawrence Ramsey]

Update: I still can't reproduce this, but I think I've narrowed it down. 
I don't believe it's related to the crash in 1.3.7, since that crash
always occurred during the reallocation inside the null_at() at the end
of display_string(), and it always originated in (IIRC)
_glibc_malloc_consolidate(), not realloc().  I also just fixed memory
corruption problems in control_mbrep() and mbrep() in 1.3.8-cvs, but
they aren't related to this, since they occur in code that doesn't exist
in 1.3.8, and I don't believe that there are any similar problems in
1.3.8, since (a) no similar crashes occur in 1.3.8, and (b) the crashes
that the bugs caused in 1.3.8-cvs occurred in free(), not realloc().

In case the aforementioned fullscreen display bug fixed in 1.3.8-cvs
does have any effect on this, I've attached a patch that should fix it
in 1.3.8.  However, without any verification that the crash is gone in a
later version, any meaningful information from valgrind, or at least a
gdb backtrace of the crash, there isn't much else I can do without being
able to reproduce it.

One last question: Does it occur in fullscreen mode in any terminal
other than gnome-terminal?  Thanks in advance.
