Thank you! Increasing coverage in tests is always great.
================
Comment at: clang/test/Analysis/NewDeleteLeaks.cpp:196
+
+namespace symbol_reaper_lifetime {
+struct Nested {
----------------
Could you please add some explanation for the test case? Thinking of the
related patch, something like this could be a good explanation:
```
Check that memory leak is reported against a symbol if the last place it's
mentioned is a base region of a lazy compound value, as the program cannot
possibly free that memory.
```
And below, we should mention that `p` is that symbol and `p->data` is the lazy
compound value.
================
Comment at: clang/test/Analysis/symbol-reaper-lambda.cpp:8
+
+int strange(Dummy param) {
+ Dummy local_pre_lambda;
----------------
Maybe it is just me, but this test case is a bit hard to follow. I guess it is
a result of creduce. But still, could you please elaborate the following:
# What is the lazy compound value? (My weak guess is `param`)
# What is the base region?
# Which symbol is being reaped and where?
================
Comment at: clang/test/Analysis/symbol-reaper-lambda.cpp:14
+ escape(param, local_pre_lambda);
+ return ref_captured; // no-warning: The value is not garbage.
+ };
----------------
Did D132236 produce an FP warning for this?
