Created an attachment (id=35793)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=35793)
different crash

BTW when I was bisecting and head was at commit "r300g: fix emission of some
non-CSO atoms at the beginning of CS" it also crashed (after longer time) but I
did git bisect good, because this crash looks different.

There are 2 issues:

1. Dummy vertex shader compilation was broken.

2. SIN and COS instructions haven't been implemented for vertex shaders. I am
really surprised because I thought we had them. Nevertheless r300 supports them
in HW directly (instructions ME_SIN and ME_COS) so their implementation should
be straithforward.

'1' should be fixed. Can you please try current mesa git?
