Comment # 13 on bug 93352 from Ilia Mirkin

I've pushed out a fix for the issue that triggers this assertion:

GridAutosport: ../../../../src/mesa/state_tracker/st_glsl_to_tgsi.cpp:2342:
virtual void glsl_to_tgsi_visitor::visit(ir_dereference_variable*): Assertion
`var->data.location != -1' failed.

But it sounds like there are additional issues too? I would encourage you to
continue using --enable-debug as that is a lot better at identifying problems
at their source.
