--- Comment #3 from Kenneth Graunke <kenneth at whitecape.org> ---
I've posted a fix for the crash to the mailing list:
http://lists.freedesktop.org/archives/mesa-dev/2014-March/056286.html

However, this won't fix your application.  It's trying to use the default
vertex array object (VAO); core profile requires you to create and bind your
own.

Because of this, you're getting an GL_INVALID_OPERATION from
glVertexAttribPointer, and your vertex data is never getting specified.  This
is easily seen when replaying the apitrace:

0 371 glVertexAttribPointer(index = 0, size = 3, type = GL_FLOAT, normalized =
GL_FALSE, stride = 24, pointer = NULL)
371: warning: glGetError(glVertexAttribPointer) = GL_INVALID_OPERATION
