Hi
I don't see how any of those errors are (lib)curl's fault. The first range
is libc problems, and AFAIK we are calling the proper cleanup function for
OpenSSL.
Okay, I think I, at one point, hesitated to open a bug because I
assumed it was a known libc bug, but then was doing memory tests on my
application again today and couldn't see why I thought that.
I just ran wget with the same errors as curl, so you seem to be right.
I'm including a 10 line use of getaddrinfo (hacked copy of the file
from #304022), which displays the bug when run with
valgrind --leak-check=full --show-reachable=yes ./addr
(Note that there are no memory leaks; this was #304022).
wget gives:
