Here is an example: mysql-5.6.6-m9/plugin/semisync/semisync.cc:30:40: warning: narrowing conversion of =91239u=92 from =91const unsigned char=92 to =91const char=92= inside { } is ill-formed in C++11 [-Wnarrowing] There are lots of others. We added "-Wno-error=3Dnarrowing" to the COMMON_C_FLAGS and COMMON_CXX_FLAGS to get a debug build to build without errors. Rich Prohaska
