Can not generate metal shader. #4

Closed minggo closed 5 years ago

minggo commented 5 years ago

It is strange that, the same GLSL shader can not be converted to metal shader sometimes. The usage of glsl-optimizer codes is here.

I think it is because some parameters are not initialized, so it works sometimes.

it is a memory issue, you can not use the memory that has already been freed at line36 and 38 in ShaderModuleMTL.mm.

Yep, good catch.
