Created attachment 33897 [details] patch to pass fix by appending #include <sstream> to gcc/ipa-chkp.c
Look at the analysis in PR63699. It's probably the same cause for the problem, and hence the same fix.
Patch posted at https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00661.html. Note that the alternate approach of modifying gcc/system.h to include <string> conditionally on __cplusplus before "safe-ctype.h" causes bootstrap breakage elsewhere on darwin.
