This issue was fixed upstream[2] and I have cherry-picked the patch.
The alternative to resolve this issue is to release a new upstream version.
The attached patch can be applied to achieve the following:
* d/p/0001-Rewrite-to-remove-return-from-finally-block-Issue-57.patch:
apply upstream patch to resolve the parser failure (LP: #2143696).
Thanks for considering the patch.
