Hi,
s-nail 14.8.8-1.
5ecb39d3c90888d58f1028990a1dc3843ad163fe /usr/bin/mail
I was entering the Subject when prompted, and corrected a typo using
backspace and replacing the deleted characters, as I continued typing,
the error appeared. I've replaced the a-z characters I typed with
abc... for privacy, but the `+' and spacing are the same.
$ mail foo
Subject: + abcdefg hijkl mnopq*** Error in `mail': realloc(): invalid next

$ rs
The `rs' is the rest of my typing. I can't trivially reproduce. I've
annotated the "mail[...]" addresses in the backtrace with their
