From 0fce0e589353d772ceda4d493b147138406b22fd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Moritz=20Wanzenb=C3=B6ck?= Date: Wed, 11 Jul 2018 11:57:46 +0200 Subject: [PATCH] Add missing return statement in numpy import This adds a missing return statement in the python3 specific import logic of boost.python.numpy. For python3 wrap_import_array() needs to return a pointer value. The import_array() macro only returns NULL in case of error. The missing return statement is UB, so the compiler can assume it does not happen. This means the compiler can assume the error branch is always taken, so import_array must always fail. --- src/numpy/numpy.cpp | 1 + 1 file changed, 1 insertion(+) diff --git a/src/numpy/numpy.cpp b/src/numpy/numpy.cpp index 8e259bc75..3ae2295e3 100644 --- a/libs/python/src/numpy/numpy.cpp +++ b/libs/python/src/numpy/numpy.cpp @@ -19,6 +19,7 @@ static void wrap_import_array() static void * wrap_import_array() { import_array(); + return NULL; } #endif
