Subject: Fix a possible null pointer dereference found by the analyzer.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a2338bc4c2887937478d302901fb41a53e14e6d6;p=clang

Fix a possible null pointer dereference found by the analyzer.

When computing the other parameters, ‘op’ is checked for being null before it’s dereferenced.
