cython error when building horton-2.1.0 on Mac OS High Sierra about horton

It seems that you are hitting a bug in Cython. Our extension is crashing the Cython compiler, without giving any understandable output on what is going wrong.

Could you try rolling back to an older version of Cython, to see in which Cython release the problem was introduced? (We've hit another bug in Cython some time ago and the only solution was to blacklist that Cython version.)

I just checked the Cython issue tracker and there are several comparable open issues with Compiler crash in AnalyseDeclarationsTransform but none of them seem directly related.

It seems that all 0.28.* versions of Cython have this problem. The most recent working one is 0.27.3.

Dear Toon,

Thank you for the help. I rolled back to cython-0.27.3 and tried to build, but then I hit the index_wrap issue #282. Rolling back all the way to cython-0.25.2 solves the issue for horton-2.1.0.

Cheers, Hugo

I just made a bugfix release (horton 2.1.1) that should compile with the latest Cython version.
