Hi,
After spending the better part of the evening finding a bug caused by
an uninitialized pointer I would love to get a Warning about
uninitialized variables from g++ in cases like Foo, Bar and Baz below:
[EMAIL PROTECTED]:~% cat foo.cc
class Foo {
Foo() { }
int *p;
};
class Bar {
Bar() { *p = 1; }
int *p;
};
class Baz {
Baz() { }
int get_p() { return *p; }
int *p;
};
[EMAIL PROTECTED]:~% g++ -g -O2 -W -Wall -Werror -Wuninitialized -c foo.cc
[EMAIL PROTECTED]:~% g++ --version
g++ (Debian 4.3.2-1) 4.3.2
Copyright (C) 2008 Free Software Foundation, Inc.

In Foo the variable is just uninitialized, in Bar it is definetly used
uninitialized and in Baz it might be used uninitialized. Is there any
-W switch to make g++ detect such errors or is that a shortcomming of
-Wuninitialized?
