Comment # 1 on bug 1070450 from Michael Schr�der

I think there is a double free in the terminfo library triggered by screen. The
following little program shows it if run with valgrind:

#include <stdlib.h>
#include <curses.h>
#include <term.h>

char b1[2048];
char b2[2048];

int main()
{
  tgetent(b1, "xterm");
  tgetent(b2, "notfound");
  tgetent(b2, "screen");
  tgetent(b1, "xterm");
  tgetent(b2, "notfound");
  tgetent(b2, "screen");
  tgetent(b1, "xterm");
  return 0;
}
