             Bug #: 52977
           Summary: internal compiler error: Segmentation fault with `-x
                    c-header' or `-x cxx-header' option
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c

Output of -v option and preprocessed file

The following code causes an ICE with GCC 4.8.0 20120408 (experimental) and `-x
c-header' or `-x cxx-header' option.


////////////////////////////////////////
typedef int __m64 __attribute__ ((__vector_size__ (8), __may_alias__));
__inline __m64 __attribute__((__gnu_inline__, __always_inline__,
__artificial__))
_mm_setzero_si64() { return (__m64)0LL; }
////////////////////////////////////////


N.B. As far as I can confirm, this ICE is not reproduced with GCC 4.6.3, GCC
4.7.0 and GCC 4.8.0 20120311. This reproducer originally comes from a
Boost.Math 1.49.0 source file.
