Warning Chrome : Invalid asm.js: Unexpected token

[ghost]

I've compiled multiple sources without rewriting this warning, but in my file, Chrome returns a warning, everything works anyway OK in Firefox and Edge.

chrome 61 : Emscripten 1.37.21 : window 10 pro

 while((ptr|0) <= (block_aligned_end|0)) {
