Description of problem:
A call to a function to get time/date from a curses screen where there is first
a call to scr_dump() will cause the program to core dump. If the curses screen
does a getch() before the call to the time function the program will not crash.
However, there are many occasions where one will need to set up a time/date
string without making a call to getch() first. There is some kind of conflict
between the curses screen dump feature and the time functions. This is a
problem for RH to solve.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Set up a screen with curses control.
2. Do a screen dump (scr_dump(const char filename). (Do not do a getch() before
the screen dump.
3. Call a (void) function to set up a string containing the time and date.
4. The program will crash.
5. Have a call to restore(filename) after the call to the time function.
Actual Results: Crash!
Expected Results: Program should return from time fucntion and restore screen
as before dump.
Example program is avialable if you will send me your email address.

This is fixed in ncurses 5.3 (Redhat does not deliver ncurses 5.3).
