--- Comment #1 from Matt Turner <mattst88 at gmail.com> ---
Thanks for the report. It's really nice to get shader_test files that
demonstrate the bug. :)

We're storing temps[] to scratch space -- I expect that has more to do with the
problem than int() or floatBitsToInt().

I'll hopefully take a closer look at this soon. If there's a smaller test case,
that'd be nice as well.


As an aside: we're almost certainly going to generate better shader code for a
uniform array than a non-const temporary array. Assuming you hit this bug in a
real application, it's something you might want to change if possible.
