pygame.draw.aaline(⋯) segfault for 24-bit surfaces

[geometrian]

The following example causes a segfault (Python 3.12.5, pygame-ce 2.5.1):

import pygame

surf = pygame.Surface( (315,271), depth=24 )

#Crash on following line:
pygame.draw.aaline( surf, (255,0,255), (100,207),(20,229) )

Some coordinates can be passed safely, while others cannot. When it works, it seems to draw a line with the correct locations, but blended incorrectly. Meanwhile, 32-bit surfaces do not have this problem. This tells me that this function is not respecting the pixel stride.

I haven't looked at how or why, but I'm sure if you added the result of pygame.print_debug_info() to the PR description it would help contributors :)

Hello,

Thanks for the report ! This is something we're already aware and I'm currently working on a fix, which should be available in the next pygame-ce version.

The PR in question : #3008
