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</pre>
