>Description:
Since the bugfix for c++/9367 you'll see the following message if you compile the attached testcase with "g++ -c test-vprintf.cpp -O2 -ansi -pedantic-errors":
test-vprintf.cpp: In function `int vprintf(const char*, __va_list_tag*)':
test-vprintf.cpp:19: error: declaration of `int vprintf(const char*,
__va_list_tag*) throw ()' throws different exceptions
test-vprintf.cpp:16: error: than previous declaration `int vprintf(const
char*,
__va_list_tag*)'
Reportedly it happens on alpha-linux, powerpc-linux and x86_64-linux, but not on i686-linux.
>How-To-Repeat:
typedef __builtin_va_list __gnuc_va_list;
extern "C"
{
struct FILE
{
int _flags;
};
extern struct FILE *stdout;
extern int vfprintf (FILE *__restrict __s, __const char *__restrict __format,
__gnuc_va_list __arg) throw ();
extern int vprintf (__const char *__restrict __format, __gnuc_va_list __arg) throw ();
inline int vprintf (__const char *__restrict __fmt, __gnuc_va_list __arg) throw ()
{
return vfprintf (stdout, __fmt, __arg);
}
}
