Thanks for this library :)
I'm trying to use it to optimize GLSL that resulted from Rust being compiled to SPIR-V and then to GLSL.
But it fails in this line:

glsl-optimizer/src/util/ralloc.c

Line 95 in 0727229

assert(info->canary == CANARY);

This is the GLSL code:

(The same happens when I use #version 120 as compilation target.)

Any idea how to make it work? :)

Btw, I'm calling it through the glslopt crate like this:

pub fn optimize_glsl(glsl: String) -> Result<String> {
    let res = Context::new(Target::OpenGles30).optimize(ShaderType::Fragment, glsl);
    println!("GLSL optimization log:\n{}", res.get_log());
    ensure!(res.get_status(), "GLSL optimization failed. bad status");
    let glsl = res.get_output()?.to_string();
    Ok(glsl)
}
