draw_text() errors out with invalid pointer.

[Mungari]

Bug Report

Following the tutorial. I'm doing the score section, I copy-pasted the code and it errors out with an invalid pointers and dumps the core.

I thought I had problems with a variable, but even with normal text it sometimes errors out.

Platform: Fedora 31
Arcade version: arcade==2.3.15
Python version: 3.7

Stack trace as per journalctl:

Process 7112 (python) of user 1000 dumped core.

Actual behavior:

Expected behavior:

Print the score to the screen

Steps to reproduce/example code:

score_text = f"Score: {self.score}"
        arcade.draw_text(score_text, 10 + self.view_left, 10 + self.view_bottom,
                         arcade.csscolor.WHITE, 18)

[pvcraven]

Does this happen the first time you attempt to draw text? Or after the game runs for a while?

[Mungari]

It happens every time I try and run the game. Sometimes right after I make a step, sometimes right after it loads.

If I try and use normal text like "Hello" sometimes it works, sometimes it doesn't.

[pvcraven]

I added a lot of print debug statements. Can you try running with this?

[pvcraven]

That narrows it down. It fails on just the second attempt?

I've added more debug messages to this upload, if you've got time to try it.

[Mungari]

Doesn't work, still. Sometimes it runs, I can collect a few coins and then it dies. Sometimes it doesn't start at all, some other times it crashes only after I move

[pvcraven]

Did the second wheel print out additional debug messages?

[Mungari]

When it crashes right after I launch the game:

Hope this is useful :)

[einarf]

python-pillow/Pillow#4225 looks relevant

EDIT: Try python-pillow/Pillow#4225 (comment)

[pvcraven]

Dumps with the new wheel I linked should look different than what you printed. It will still crash, but should give more debug info.

[pvcraven]

And yes, that seems to be the same bug perhaps.

[Mungari]

Tried following that. This is the result of trying to install Pillow 6.2.0:

[einarf]

Missing the python dev/devel package I guess. Not sure what that is called on fedora.

[Mungari]

It works now! Thanks :D very helpful!

[einarf]

Great! The jam is saved I guess? 😄

[sangkips]

Install sudo dnf install python-devel will solve the issue
