            Bug ID: 109693
           Summary: Hang of the graphics driver and assertion on
                    si_upload_vertex_buffer_descriptors
           Product: Mesa

glxinfo output

After this [1] commit, the GL tests we have on gstreamer started to causing a
hang in my machine (Gstreamer issue [2]). I was running mesa 18.2.8 and it was
constantly hanging upon running those specific tests. Once I upgraded to mesa
18.3.3 half the times it hangs and the other half it hits the following
assertion. Compiling and running against mesa 19.0 rc5 didn't change things.

pipelines_gl_launch_lines:
../src/gallium/drivers/radeonsi/si_descriptors.c:1150:
si_upload_vertex_buffer_descriptors: Assertion `num_records >= 0 && num_records
<= UINT_MAX' failed.

the whole log is [here] [3]

To reproduce you can run the following:

```
git clone https://gitlab.freedesktop.org/gstreamer/gst-build.git
cd gst-build
meson build -Dintrospection=disabled -Dgtk_doc=disabled -Dexamples=disabled
-Dsharp=disabled
ninja -C build/
./gst-uninstalled.py gst-validate-launcher check.gst-plugins-base.pipelines_gl*
-fs --mute --dump-on-failure --no-display --meson-no-rebuild -M
"/tmp/validate-output/"
```
