Approval Request Comment
[Feature/regressing bug #]: Bug 1062355
[User impact if declined]: Ill-formed WebGLSL can crash Firefox by causing the stack to be exhausted.
[Describe test coverage new/current, TBPL]: Tested against WebGL Conformance suite as well as https://www.khronos.org/registry/webgl/sdk/tests/conformance/glsl/bugs/nested-functions-should-not-crash.html
[Risks and why]: Low. Replace crash with WebGL error when compiling ill-formed source.
[String/UUID change made/needed]:
