Related issues

It seems related to the handlebar issue on 1.1.1 (https://github.com/compodoc/compodoc/issues/521) since I had the heap out of memory issue using 1.1.1 and based on the stack trace this is also coming from handlebars

Suggest a Fix

[vogloblinsky]

I have activated the strict mode for handlebars. The bug seems related to JsdocCodeExampleHelper helper. I will have a look today.
