--- Comment #3 from Evgeny Bobkin <evgen.i...@gmail.com> ---
another issue is that if there two lines
glGenVertexArrays (1, &vao_id);
glBindVertexArray (vao_id);
from lines 46-47 are removed and the cube is drawn with
glEnableVertexAttribArray (position_id);
glBindBuffer (GL_ARRAY_BUFFER, vertex_buffer);
glVertexAttribPointer (position_id, 3, GL_FLOAT, GL_FALSE, 0, nullptr);
glEnableVertexAttribArray (color_id);
glBindBuffer (GL_ARRAY_BUFFER, color_buffer);
glVertexAttribPointer (color_id, 3, GL_FLOAT, GL_FALSE, 0, nullptr);
glDrawArrays (GL_TRIANGLES, 0, 36);
instead of
glBindVertexArray (vao_id);
glDrawArrays (GL_TRIANGLES, 0, 36);
the test case app breaks with a segmentetion fault while using opnegl 3.3
context, however both ways work just fine with the old created context!!
