New Revision: 148695

URL: http://llvm.org/viewvc/llvm-project?rev=148695&view=rev
Log:
Add a test for CFStringCreateCopy.
Normally this function should not create copies of constant strings, but it does when the default CFAllocator
is replaced (e.g. under AddressSanitizer)

This test is related to http://code.google.com/p/address-sanitizer/issues/detail?id=10
