Steps to reproduce

URL:

Repro Steps:

  1. Open Edge on build 10532
  2. go to https://brionv.com/misc/asm.js/test1/
  3. “Hello, world!” appears only once

Note this seems to occur on 10240 also with the asm.js optimizations enabled.

Opening the F12 dev tools re-disables asm.js optimizations, so not sure if there’s anything going into the console that I can’t see.

Expected Results:

An asm.js module, like any other JavaScript function, should be able to execute multiple times. In the test case https://brionv.com/misc/asm.js/test1/ you should see “Hello, world!” appear ten times.

Actual Results:

Dev Channel specific:

Yes
