            Bug ID: 101464
           Summary: PrimitiveRestartNV inside a render list causes a crash
           Product: Mesa
           Version: 17.0
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: o.lauffenburger at topsolid.com
        QA Contact: mesa-dev at lists.freedesktop.org

When using glDrawElements with glPrimitiveRestartIndexNV during the compilation
of a render list, there is a crash when Mesa reaches the second restart index
of the array.

The reason is that when PrimitiveRestartNV is called internally the first time,
save_PrimitiveRestartNV() (in \src\mesa\vbo\vbo_save_api.c) is called. It
executes _save_End() and _save_Begin(curPrim), but _save_Begin() is a noop
function that merely raises an OpenGL error "Recursive glBegin".
