[cfe-dev] ast-dump issue...

[Fons Rademakers]

Hi,

  using clang from the trunk of today, I get when doing:

clang-cc ll.cxx -ast-dump

an assertion failure in DeclPrinter.cpp:

typedef __int128_t __int128_t;
typedef __uint128_t __uint128_t;
struct __va_list_tag {
public:
     struct __va_list_tag;
     unsigned int gp_offset;
     unsigned int fp_offset;
     void *overflow_arg_area;
     void *reg_save_area;
     inline __va_list_tag();
     inline __va_list_tag(struct __va_list_tag const &);
     inline struct __va_list_tag &operator=(struct __va_list_tag const &);
     inline ~__va_list_tag();
};
typedef struct __va_list_tag __va_list_tag;
typedef __va_list_tag __builtin_va_list[1];
typedef signed char __int8_t;
typedef unsigned char __uint8_t;
typedef short __int16_t;
typedef unsigned short __uint16_t;
typedef int __int32_t;
typedef unsigned int __uint32_t;
typedef long long __int64_t;
typedef unsigned long long __uint64_t;
typedef long __darwin_intptr_t;
typedef unsigned int __darwin_natural_t;
typedef int __darwin_ct_rune_t;

Do I miss some specific additional command line options or is this a real 
issue?

The ll.cxx file is attached.

Cheers, Fons.
