en Copyright 2015 Java http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Analysis/new-dynamic-types.cpp#f01831eb [analyzer] Don't crash when dynamic type of a variable is set via placement new.If a variable or an otherwise a concrete typed-value region is beingplacement-new'ed into, its dynamic type may change in arbitrary manners. Andwhen the region is used, there may be a third type that's different from boththe static and the dynamic type. It cannot be *completely* different from thedynamic type, but it may be a base class of the dynamic type - and in this casethere isn't (and shouldn't be) any indication anywhere in the AST that there isa derived-to-base cast from the dynamic type to the third type.Perform a generic cast (evalCast()) from the third type to the dynamic typein this case. From the point of view of the SVal hierarchy, this would haveproduced non-canonical SVals if we used such generic cast in the normal case,but in this case there doesn't seem to be a better option.Differential Revision: https://reviews.llvm.org/D43659llvm-svn: 326245 List of files: /llvm-project-15.0.7/clang/test/Analysis/new-dynamic-types.cpp Tue, 27 Feb 2018 20:54:40 +0000 Artem Dergachev <artem.dergachev@gmail.com>
