Summary: Regression: GLSL linker aborts when linking a single
vertex program containing a varying.
Product: Mesa
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: mesa-dev@lists.freedesktop.org
ReportedBy: nbow...@draconx.ca

Test case
When attempting to link a program object using a single vertex shader that has
a 'varying' object, the GLSL linker instantly aborts:
varycrash: program/ir_to_mesa.cpp:1467: virtual void
ir_to_mesa_visitor::visit(ir_dereference_variable*): Assertion
`ir->var->location != -1' failed.
This is a regression from mesa 7.8, presumably due to the recent glsl2 merge.
I can bisect it later if necessary. Occurs on at least swrast and i965.
