**Short description of error**
a bunch of the tests involving SSS are failing on X86/Windows, The cause seems to be a buffer overflow but there is something else going on as well
Root cause: `sizeof(Bssrdf)` = 88 which is > `sizeof(ShaderClosure)` (which is 80)
sofar classic buffer overflow, the question now is, why aren't we seeing this on X64?
For some reason on X64 `sizeof(ShaderClosure)` has grown to 96, both unexpected according to the comments around it and neatly sidestepping the buffer overflow that plagues x86.
