Crash dump was written to: erl_crash.dump

Hello.
Sync crashes when a cowboy handler with erlydtl is run.
I made a repo to make it easier to reproduce: https://github.com/koddo/tmp-erlydtl-sync-crash-test
From it's readme:
There are two handlers: http://localhost:8080/with_erlydtl and http://localhost:8080/without_erlydtl
When the one with erlydtl is run, the sync crashes the node.
