<pre>Hi,
for this program:
void __attribute__ ((__noreturn__)) f();
void __attribute__ ((__noreturn__)) exit(int status) throw();
void exit(int status) throw()
{
f();
}
I get the following warning:
clang++ -c warn.cpp
warn.cpp:5:6: warning: 'exit' is missing exception specification 'throw()'
void exit(int status) throw()
^
throw()
warn.cpp:3:37: note: previous declaration is here
void __attribute__ ((__noreturn__)) exit(int status) throw();
^
1 warning generated.
Adding __attribute__ ((__noreturn__)) to the definition of exit() gets rid of
the warning. But is this required at all? Either way, it should not warn about
the throw().
<a class="bz_bug_link

title="RESOLVED FIXED - bad interaction bt attribute noreturn and throw specification"
href="show_bug.cgi?id=8829">Bug 8829</a> looks very similar.
Best regards,
Martin</pre>
