Subject: Fix usage of PyMem_Malloc() in os.stat()
X-Git-Tag: v3.6.0a1~458
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c36674a2c52ecb30e180b3bcced2b8c529cf72fb;p=thirdparty%2FPython%2Fcpython.git

Fix usage of PyMem_Malloc() in os.stat()

Issue #26563: Replace PyMem_Malloc() with PyMem_RawMalloc() in the Windows
implementation of os.stat(), since the code is called without holding the GIL.
