This archive contains the .cpp file and the makefile described above

Hello, I'd like clang's static code analyser to be able to detect use of
references to an automatic variable outside of its scope. I've attached a
test-case that shows a bit of code that takes pointer to an automatic variable
and use that pointer outside the scope of the original automatic variable. I
have also attached a make file that compiles the .cpp file so that it can be
run with scan-build to run the static code analyser on the .cpp file.
