            Bug ID: 35644
           Summary: Incorrect warning generated for methods with noexcept
                    signature and catch all handler
           Product: clang
           Version: 5.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

Created attachment 19539
  --> https://bugs.llvm.org/attachment.cgi?id=19539&action=edit
sample source file to compile demonstration

If the code below ( and attached 'main.c' ): 

void f() noexcept
{
    try {
        throw;
    }
    catch (...) {
    }
}

is compiled with clang 5.0.1RC3 the following warning is generated: 

" 'f' has a non-throwing exception specification but can still throw
[-Wexceptions]"

which is incorrect since the throw call is caught by the catch-all handler,
therefore qualifying as non-throwing. 

g++, 4.8.2 at least, does not emit any warning. 

Kind regards
