Re: [MacRuby-devel] That bus error: Reproducible and with all gl calls!

I also reproduce this on the experimental branch, and it's crashing inside OpenGL. Maybe something needs to be done first, before calling OpenGL? I know it's working nice inside a Cocoa application context.

I reproduce the same crash with Ruby 1.8 + RubyCocoa too:

$ ruby -r osx/cocoa -e "OSX.require_framework 'OpenGL'; p OSX.glMatrixMode(OSX::GL_PROJECTION)"

And also with a simple C program: ~/tmp% cat e.c #include <OpenGL/gl.h> int main() { glMatrixMode(GL_PROJECTION); return 0; } ~/tmp% cat e.c #include <OpenGL/gl.h> int main() { glMatrixMode(GL_PROJECTION); return 0; } ~/tmp% gcc -framework OpenGL -o e e.c ~/tmp% ./e zsh: bus error ./e So as Laurent said, it's probably just an initialization problem.
