Well, I think there is a problem with the current master
since commit 38be85124551083d269.

The problem is that the by-backend trick which were tolerated before
does not work anymore.

Tested between Org 9.1.6 as in current emacs-26.0.91 release versus current
Org master.

More over, ignoring the no-eval parameter
in org-babel-parse-header-arguments
restores the previous behavior.

Regards,

Fabrice
