Since commit https://github.com/python/cpython/commit/c02b41b1fb115c87693530ea6a480b2e15460424 , some syntax errors are preventing cpython from compiling with --enable-framework on. 

Specifically, the errors are in Modules/getpath.c on line 1134 and 1165.

I've made some inline comments on github as well.

Oh, I expected that we had macOS buildbots building Python with --enable-framework. Thanks for the reporting the issue.

I wrote PR 16695 which should fix the issue, but I cannot test my fix right now.

I'm now getting double free on the same function:

Hum, getpath.c seems to use deprecated APIs:

bpo-38353: Fix typos in calculate_argv0_path_framework() (GH-16695)
https://github.com/python/cpython/commit/b6e0fc74265db96fdd0e0b8151c768c583ad80f0

Thanks for the bug report Haruka Ma, it should now be fixed.

W.r.t. the deprecated APIs in getpath.c: Issue15498

That issue contains an ancient patch to switch to non-deprecated APIs, but we haven't had time yet to fully test these. The issue also mentions that Apple's install of Python already switched away from the deprecated APIs, but had some issues at the time.
