10440,"boyer_moore.hpp fails on Linux w/ gcc-4.7.2, OK with Mac clang",boost@…,Marshall Clow,"I have a simple find-string-in-file program that uses boyer_moore matching.  On Mac, it compiles and works OK.  (Not sure if Mac is really using gcc; that's the command name, but ""gcc -v"" says ""Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)""

At any rate, the same code, with a freshly-compiled Boost-1.56.0 on Debian 7, gcc-4.7.2, fails to compile:

(On Mac also, I compiled a fresh copy of Boost-1.56.0 using the native compiler.)
