### Description <!-- Shortly describe your issue. --> This is a regression issue. Build dynamic failed. ### Test Code <!-- List the impacted test cases or sources code here. For example: --> [/modules/Assert.js](https://github.com/intel/zephyr.js/blob/master/modules/Assert.js); [/tests/test-timers.js](https://github.com/intel/zephyr.js/blob/master/tests/test-timers.js); Simple test.js: runJS('timer.js'); ### Steps to Reproduction <!-- Describe the exact steps how to reproduce the issue(if any precondition for this issue, please make sure put them firstly). --> 1. Copy /modules/Assert.js to a101 board as assert.js 2. Copy /tests/test-timers.js to a101 board as timer.js 3. Build simple test.js and flash it to a101 board. `make dynamic JS=samples/test.js ROM=256` ### Actual Result <!-- Describe the actual behavior you get. --> Build failed:  ### Expected Result <!-- Describe what the behavior would be without the issue. --> Build dynamic successfully. ### Test Builds <!-- Include GitHub branch, commit id, target device, test date and result. If the result is fail, please use 'Fail', opposite is 'Pass', and use 'Crash' for crash issue. More than one builds can be listed here for history reference. --> Branch | Commit Id | Target Device | Test Date | Result ---|---|---|---|--- master | f90d9d1 | arduino 101 | Jun 12, 2018 | Pass master | 2b033e1 | arduino 101 | Jun 12, 2018 | Fail ### Additional Information <!-- Specific test environments --> <!-- Error logs, screenshots for the failure phenomenon and pass screenshot. -->
