Warning Chrome : Invalid asm.js: Unexpected token

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)) {
	HEAP32[((ptr)>>2)]=value4;                <-- Warning
	HEAP32[(((ptr)+(4))>>2)]=value4;
	HEAP32[(((ptr)+(8))>>2)]=value4;
	HEAP32[(((ptr)+(12))>>2)]=value4;
