Re: gdb 15.2 or 16.1

I'm sorry, I jumped to conclusions. It still crashes. It doesn't crash
if just run it in TUI mode without any program for debugging (just
`gdb -tui <enter>`)
But if I run it with even this simple program:
int main(void)
{
        return 0;
}

it crashes with this backtrace:

It seems there is something wrong with getmaxx() from /usr/lib/libcurses.so.9
