Delivered-To: submit@bugs.debian.org
Package: g++
Version: 2:2.95.4-8
Severity: normal
In a member function such as:
int Partition::in_which_part()
{
int i;
....
}
A return statement with type of int is required. However, the compiler
fails to give any error/warning when the corresponding return statement
is omitted, when invoked with default options.
In the current case, the compiler does not even give a warning message
by default. Giving an error message might break valid C++ code (which
I'm not sure of) but it seems that when you specify -Wall the compiler
will detect whether
src/generic/Utility.hxx:173: warning: control reaches end of non-void function `Utility::operator <<<int, less<int> >(ostream &, const set<int,less<int>,allocator<int> > &)'
I think this should be the default behavior, which may be suppressed
with a flag if desired.
Thanks,
