Subject: bpo-42591: Export missing Py_FrozenMain() symbol (GH-23730) (GH-23734)
X-Git-Tag: v3.9.2rc1~143
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6b2ed385094839c1920b934f07d946bf049a3770;p=thirdparty%2FPython%2Fcpython.git

bpo-42591: Export missing Py_FrozenMain() symbol (GH-23730) (GH-23734)

Export the Py_FrozenMain() function: fix a Python 3.9.0 regression.
Python 3.9 uses -fvisibility=hidden and the function was not exported
explicitly and so not exported.

(cherry picked from commit b5c7b38f5ebbc84b5b80192db1743d3e1cdcf4c5)
