            Bug ID: 99214
           Summary: Crash in library libswrAVX.so when assigning vertex
                    buffer object pointers with elements of type GL_DOUBLE
           Product: Mesa
           Version: 13.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/Gallium/swr
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: chris at circlecvi.com

/**pseudo snippet


glPushClientAttrib(GL_CLIENT_VERTEX_ARRAY_BIT);
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_NORMAL_ARRAY);

assert(VertexBuff size == NormalBuff size);

// Vertices binding
[Vertex Buffer Object] ->bind();
glVertexPointer(3, GL_DOUBLE, 0, NULL);

// Normals binding
[Normals Buffer Object] ->bind();
glNormalPointer(GL_DOUBLE, 0, NULL);

// !! Crash on glDrawArrays in libswrAVX.so
glDrawArrays(GL_QUAD_STRIP, 0, [Elements count]);
glPopClientAttrib();

 **/

- Crashes on GL_DOUBLE type
- Does not crash on GL_FLOAT
- Verified contents of both buffers to be correct geometry in both instances.
