[llvm-dev] [llvm-cxxdump] Error reporting, build errors on FreeBSD 11.1

[Harald van Dijk via llvm-dev]

Hi,

The obvious fix probably is correct: 
https://github.com/llvm/llvm-project/commit/f6fa95b77f33c3690e4201e505cb8dce1433abd9 
was committed yesterday which removed <string> as an implicit include 
through one of the other headers, so this file should probably be 
updated to include <string> explicitly.
