From the valgrind trace, this bug is not in the libjpeg-turbo code and is not reproducible in standalone libjpeg-turbo.  Removing myself.
Summary: JPEG triggeres multiple undefined memory usage reports [@core_combine_over_u_sse2_no_mask] → JPEG triggers multiple undefined memory usage reports [@core_combine_over_u_sse2_no_mask]
Whiteboard: [gfx-noted]
Blocks: grizzly
The PNG problems recorded are a different problem. If the test files can be located I can take a look at it. However the JPEG problem appears to be the same as in bug 1262905 -- using the CPU instead of SIMD/SSE2 version of color_convert appears to resolve the valgrind warnings.
