In console I see error

Invalid function pointer called with signature 'iiiiiiiii'. Perhaps this is an invalid value (e.g. caused by calling a virtual method on a NULL pointer)? Or calling a function with an incorrect type, which will fail? (it is worth building your source files with -Werror (warnings are errors), as warnings can indicate undefined behavior which can cause this)

It's stop crashing if I set "Enable Exception" to "Full" in publishing setting (http://d.pr/i/Tmshs), but this is not acceptable for release.

It crashes for me too in WebGL with Unity 2017.2.
Would be so great to have a working example.

[ancientc]

After eight hours of crashes and javascript error debug I ask for help.
I hereby offer 30 USD (paypal) to anyone who delivers me a project that compiles a working Moonsharp WebGL build on Unity 2017.2. ( Basic script running should work, at least 80% of Moonsharp functionality should work.)
Deadline 3.Dec 2017

I too am having this issue. Tried both the Unity store plugin and the generic dll with link.xml. No dice.

Here's my stack trace:

If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more information.```

This PR fixes the problem for me, not sure why it was never merged #146
