[G71] "Assertion `bkref' failed" reproducible with glmark2

Using glmark2 I can trigger the assertion
"glmark2: pushbuf.c:238: pushbuf_krel: Assertion `bkref' failed."
quite easily. I'm not sure if this is a duplicate of other bugs.

The fastest way to reproduce seems to be:

./glmark2 -b
buffer:columns=200:interleave=false:update-dispersion=0.99:update-fraction=0.5:update-method=subdata:buffer-usage=static
--run-forever

Changing some parameters from that command line still trigger the assertion,
but usually it takes a bit more time. The command above triggers for me
after 2.5 seconds (usually less than that), while for example the following
command

./glmark2 -b
buffer:columns=200:interleave=false:update-dispersion=0.9:update-fraction=0.5:update-method=map
--run-forever

can trigger even a minute later.

I've used glmark2 at commit f413c5b423250b4fde8f95639ad368d5b02c5b9b.

Software versions:
xf86-video-nouveau-1.0.13
mesa-13.0.3
libdrm-2.4.74
xorg-server-1.19.0

Hardware: nVidia Quadro FX 1500

Backtrace attached.
