Crash in createShader #84
Description
I find that the call to glShaderSource() in util.jl crashes Julia, since upgrading to version 1.12.1 (Linux / Windows). Naively replacing the third argument with Ptr{GLchar}[pointer(source)] seems to fix it -- although I'm not sure that this simplification fully matches the original behaviour...

Ptr{GLchar}[pointer(source)].Actually that seems to be what GLMakie is doing, although it's unsafe - surprised that it works that way.
It should need a

Apologies -- I'd been using what I now realize is probably obsolete code
createShader()fromModernGL/test/util.jl. I presume that the right thing to use here isglShaderSource(), as given inGLAbstraction.jl(noting that your above observations might also be applicable there), thank you.
