------- Comment #7 from howarth at nitro dot med dot uc dot edu 2009-02-21 20:18 ------- This problem in darwin10 is in fact due to c++ comments in /usr/include/Availability.h and /usr/include/AvailabilityInternal.h. Replacing those with c style comments allows the gcc.dg/cpp/trad/include.c -fno-show-column testcase to pass without ICE'ing.
