Bug ID: 25772
Summary: Analyzer misses writes to invalid memory
Component: Static Analyzer
Assignee: kremenek at apple.com
Reporter: t at sharklasers.com
CC: llvm-bugs at lists.llvm.org
Pointers are kept to some objects on the stack. Once the lifetime of those
objects end, the pointers are used to write to that memory.
$ scan-build g++ -std=c++1z write_invalid_mem.cpp
scan-build: Using 'local/tmp/clang/bin/clang' for static analysis
scan-build: Removing directory '/tmp/scan-build-2015-12-08-151246-7669-1'
because it contains no reports.
scan-build: No bugs found.
