ncurses 5.3 (debian linux) - segfault in getch()

[Wolfgang Gutjahr]

Hi,

after I upgraded to version 5.3 of ncurses, the getch()-function loops 
(wgetch (), _nc_wgetch (), wgetnstr(), wgetch(),..) and finally 
segfaults. It is working with stdscr only (see sample below). But my 
program uses a FILE* as argument for newterm(), which I get from a file 
descriptor of a telnet session (with fdopen).

All has worked well with ncurses 5.2.

The following program outputs -1 (correctly) with ncurses 5.2, but 
segfaults with 5.3. The outcommented version with fd 0 (stdscr) works 
with both versions:

#include <curses.h>
#include <iostream.h>

int main()
{
  FILE* m_pTerm;
  if ( !(m_pTerm = fopen("junk.txt", "w+")) )
    {
      cout << "File open error"  << endl;
      return 0; 
    }
//   if ( !(m_pTerm = fdopen(0, "w+")) )
//     {
//       cout << "File open error"  << endl;
//       return 0;      
//     }

  SCREEN* m_pScreen = newterm("vt100",  m_pTerm, m_pTerm);

  set_term(m_pScreen);
  initscr();

  keypad(stdscr, TRUE);
  nonl();
  cbreak();
  noecho();

  int n = getch();
  cout << "getch() returned " << n << endl;

  endwin();
  delscreen(m_pScreen);
  fclose(m_pTerm);

}

Any explanations and help are highly appreciated.

best regards,
Wolfgang
