Hello,
TL;DR
I encountered a bug-like behavior of a Python built-in module.
Could you reproduce it in C?
While working with Python and its curses module on FreeBSD
11-current (x86_64),
I found a weird behavior of the module. The code below doesn't
print any character
although it should print a space on the upper-left corner.
```
# test.py
import curses
window = curses.initscr()
window.attrset(curses.A_NORMAL)
window.addch(" ")
window.getch()
curses.endwin()
```
The cause is `window.attrset()` and when I removed the line it
works just fine.
And, with the visible characters (such as 'A' and '?' except for '
' and '\t'),
it works fine even if window.attrset() is there.
Hi,
I have a:
* FreeBSD-CURRENT system: built from Subversion revision r290830
* python27-2.710_1 (installed with pkg install lang/python )
* python35-3.5.0 (installed with pkg install lang/python35 )
I ran your test case, and did not encounter your problem.
For me, a space is printed in the top left.
Also, I see:

At least for me, the Python _curses.so is linking against ncurses.so.8.

I always build and install ports via the ports system using `portmaster`
and never use `pkg`.
Just now, I rebuilt lang/python27 and lang/python35.
But, still on my machine,
```

And devel/ncurses is explicitly required by them.
```

What's happening on my machine?
My uname is here.
```
