Memory leaks in Ncurses 6.1

Subject:	Memory leaks in Ncurses 6.1

Hi Everyone,

I have a bunch of build scripts I use for testing. I can build
packages like cURL, Git, GnuPG, and Wget from the ground up. Most of
the packages indirectly depend upon Ncurses due to dependencies on
iConvert and GetText.

Some of the testing I perform includes Asan and UBsan. Asan requires
the target and all dependencies to be built with Asan, and the scripts
can do that. Asan seems to cause a lot of trouble for GNU software.

Ncurses was configured with --disable-leaks, but it is failing Asan
testing like shown below.

When Ncurses leaks it breaks the testing of all programs and shared
objects that depend on Ncurses. We can't test the target programs or
libraries. Also, the memory leaks cause resource exhaustion on
platforms like Android. Managed languages like Java and .Net will load
and unload shared objects repeatedly, and the leaks accumulate until
there's no more memory. (Just ask the OpenJDK guys about OpenSSL).

Is there any way to disable all memory leaks in Ncurses?

(I'm fine with patching Ncurses and adding a destructor to perform the cleanup).
