[Bug 1999171] Re: tparm dynamic variables broken

[Avram Lubkin]

I was able to confirm this also fails on Fedora 37 with ncurses-
libs-6.3-3.20220501, so this looks like a regression in 6.3

@dickey-his, it looks like there were several changes to tparm between 6.2 and 6.3. Is it possible this could have caused the issue?
Static (uppercase) variables are working as expected, but dynamic (lowercase) variables don't seem to get set.

Title:
  tparm dynamic variables broken

Status in ncurses package in Ubuntu:
  New

Bug description:
  I use the Python curses library for convenience, but this seems to be
  an ncurses bug as Python simply wraps the ncurses library.

  As you can see from example below, the dynamic variable x gets stored as 4, but, when it's
  recalled, 0 is returned instead of 4. This was on 22.04 and 20.04 with libncurses6 6.3-2.

  I've confirm the behavior is correct on Fedora 36 with ncurses-
  libs-6.2-9.20210508. I apologize I haven't been able to narrow it down
  farther, but figured it would be good to get a bug logged in case
  someone has more insight.

  ```
  Python 3.10.6 (main, Nov  2 2022, 18:53:38) [GCC 11.3.0] on linux
  Type "help", "copyright", "credits" or "license" for more information.
  >>> import curses
  >>> curses.setupterm()
  >>> curses.tparm(b'%p1%Px', 4)
  b''
  >>> curses.tparm(b'%gx%d')
  b'0'
  ```
