STL_MSFT retitled this revision from "[libc++] Initialize local doubles to
0.0." to "[libcxx] [test] Initialize local doubles to NaN.".
STL_MSFT updated the summary for this revision.
STL_MSFT updated this revision to Diff 55506.
STL_MSFT added a comment.
Now I'm using NaN instead of 0.0 for the initializations, as suggested by
Howard.
