Description Dustin T Irwin 2020-10-26 22:19:38 UTC 
Hello! I am new to game development and experimenting using Julia and https://github.com/jonathanBieler/SimpleDirectMediaLayer.jl. I am encountering a regular crash when my game engine (GameZero.jl) tries to render a SDL Texture using Blit_3or4_to_3or4__inversed_rgb.

Error message:


Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.

Comment 1 Sylvain 2020-10-27 08:26:52 UTC 
Hello,

The best to investigate would be a small test-case. (even in Julia).
and/or the image that cause the image the issue.
Comment 2 Sylvain 2020-10-27 08:28:34 UTC 
maybe you can log some info in your code.

before calling:
SDL_CreateTextureFromSurface()

add something like:

SDL_Log("image w=%d h=%d pitch=%d", surface->w, surface->h, surface->pitch);

testcase

here's my test-case and it converts the surface with no invalid memory access.

maybe you can translate it to Julia and test it.
