This is strange, the gradient itself is already checked for NULLness at this point (when reading it from the app_server link) and I don't see anything else that would be dynamically allocated.

Most likely something down the line is getting dynamically allocated; i.e. via inlining. The code looks like it's using a bunch of SSE here, which is indicative of a lot of math going on. Is it possible to run Web+ under test_app_server?
