Looks like the problem was caused by this bug: https://github.com/dart-lang/sdk/issues/45870 affecting dfunc package. The corresponding issue is closed, but since there's only one usage of dfunc library and it can be easily updated, I've removed dependency on it for now, until the bug fix is in production.
Fixes #31
