User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2-2 i686)

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):

How reproducible:

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.

Additional info:

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).
