There is a bug in 7.9 that makes NULL config to slip. I've cherry-picked the fix to it. Do you see this on all versions? When is config NULL?

It happened in just 7.9, when I called eglCreateContext(dpy, NULL, EGL_NO_CONTEXT, attribs) -- commit 110c49fddd7a111288946255477ea3a354db49e8 seems to have fixed it, thanks! |

egl_dri2 seems to handle this fine, but egl_glx tries to dereference it in this function: static int GLX_egl_config_index(_EGLConfig *conf) { struct GLX_egl_config *GLX_conf = GLX_egl_config(conf); return GLX_conf->index; } So it segfaults when it tries to create a context on this line in GLX_eglCreateContext: GLX_ctx->context = glXCreateNewContext(GLX_dpy->dpy, GLX_dpy->fbconfigs[GLX_egl_config_index(conf)], GLX_RGBA_TYPE, GLX_ctx_shared ? GLX_ctx_shared->context : NULL, GL_TRUE);
