backtrace from snprintf call with invalid maxlen

(In reply to Damien Miller from comment #1)
> I'm not able to replicate this. Are you able to get a stacktrace?

yes. I recompiled from source on commit
6dfb65de949cdd0a5d198edee9a118f265924f33 and edited progressmeter.c,
changing can_output to always return 1, and editing setscreensize to
always set win_size to 121. line numbers should still match the
unedited version.

I built it with:
configure --prefix=/home/jacob/projects/openssh/dbg CFLAGS='-g -O0'
--with-privsep-path=/run/sshd --disable-strip

created a file:
touch ～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～
and debugged the built scp with args:
/home/jacob/projects/openssh/dbg/bin/scp
～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～ localhost:

Attached the backtrace
