Comment 2 Ian Romanick 2014-05-05 17:12:02 UTC
D'oh.  It looks like I disabled the 'make check' part of my build script while I was doing a long bisect, and I never re-enabled it.  I'll take a look at this.
Comment 3 Ian Romanick 2014-05-07 16:51:51 UTC
Fixed on master by the commit below.  This patch has also been cherry picked to the 10.2 branch.

commit f7bf37cb13ff4e727d640a3bd02980aba0c0b4ce
Author: Ian Romanick <ian.d.romanick@intel.com>

    linker: Fix consumer_inputs_with_locations indexing
    In an earlier incarnation of populate_consumer_input_sets and
    get_matching_input, the consumer_inputs_with_locations array was indexed
    using the user-specified location.  In that version, only user-defined
    varyings were included in the array.
    In the current incarnation, the Mesa location is used to index the
    array, and built-in varyings are included.
    This change fixes the unit test to exepect gl_ClipDistance in the array,
    and it resizes the arrays to actually be big enough.  It's just dumb
    luck that the existing piglit tests use small enough locations to not
    stomp the stack. :(
