Question: Internet explorer 11 (latest) crashes with the message "Internet Explorer has stopped working" when opening developer tools and and I have my site open.
Chrome, Edge doesn't give the problem.

All the functionality in my site works correctly.

This is only with my site (intranet site)

When I debug it I get

> 
> Unhandled exception at 0x5B514C32 (mshtml.dll) in iexplore.exe: 0xC00000FD: Stack overflow (parameters: 0x00000001, 0x06EC2FFC).

How can I troubleshoot what in my site causes this behavior?

I have tried resetting Internet Explorer and disabling all add-ins but because the issue is not to do with other sites I can only think the issue is to do someone specific in the html/ javascript in my site.

Answer: 
This bug [has been reported](https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/7115476/) to Microsoft and a demo is linked on the page. The Microsoft Edge Team provided the following statement:

> 
> Thank you for the feedback. This appears to be fixed in Edge as I am not able to repro this. Please note that we are not working on IE feature bugs any longer unless they are security related. As a result this item will be closed out as not repro to reflect the testing results from Edge.

It doesn't look like we'll see it resolved by Microsoft.
In my case, just when I delete line

```
<link rel="stylesheet" href="./css/font-awesome.min.css">

```

then I open Developer tools (F12) and then I restore the deleted line, the IE stays running!
