Description

I have attached a sample project that demonstrates this problem. When you run the app in Run mode the app works fine. When you run the app in Debug mode the app will crash at startup. The crash is a result of this line of code in underscore.js: render = new Function(settings.variable || 'obj', '_', source); Here is the stack trace for the breakpoint I set and stepping over or into the line will crash the app.

I was able to reproduce this issue with current GA stack: Appcelerator Studio, build: 4.5.0.201602170821 Appc CLI NPM: 4.2.4 Appc CLI Core: 5.2.2 Arrow: 1.7.29 SDK: 5.2.2.GA Node: v4.4.0 OS: El Capitan (10.11.4) Xcode: 7.3.1 Device: iphone 6s (9.3.1) Notes: * You do not need to set a breakpoint to reproduce this issue. If you debug the attached app without any breakpoints, the app will crash on launch. * In the attached app, if you comment out <Label text="Value is {bookTitle} ranked {ranking}"/> in index.xml and debug the app again, the app will launch without any issues. * On crash, I also get the EXC_CRASH (SIGABRT); see [^wilson.crash]

Hello, this bug is no longer present in iOS 5.4.X with main-thread enabled. This actually relates to another ticket created by your self, the fix also works for this issue as its the same crash regarding bad string extraction. Thank you! Enable Main-Thread in 5.4.X: <property name="run-on-main-thread" type="bool">true</property>

[~apetkov], Yep, can't reproduce this issue anymore on SDK 5.4.0.v20160531130657.

[~wluu] Great, thank you. Resolving the issue as fixed in 5.4.0!
