Error seems linked to icu (went from 58 to 65) but I can't figure out how to work around it

Is only php56-intl affected or are the other phpXX-intl versions also affected?

Maybe old versions of PHP are not compatible with the new ICU. If so, maybe we can find out how they fixed newer versions and backport the fix.

I have the same problem with php70-intl.

[ryandesign (Ryan Carsten Schmidt)]

It might be ​this bug which was fixed in php 7.2.

[ryandesign (Ryan Carsten Schmidt)]

I have been able to fix this for php55, php56, and php70 by backporting the fixes already in php71 and later. I have not committed it yet because I'm still trying to solve the problem for php53 and php54.
