Subject: [analyzer] Add regression test for the crash in PR16664.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=062ef6e6d956b8873e33fe84574c7630d2829d3d;p=clang

[analyzer] Add regression test for the crash in PR16664.

This goes with r186925, which reverted Pavel's commit in r186498.

Also, add a correctness test for the future.
