Subject: [Bug c++/23679] New: c++ "is used uninitialized" warning on arrays hard to read
X-Bugzilla-Reason: CC
X-SW-Source: 2005-09/txt/msg00106.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

cat > foo.c << EOF
int main() {
  int f[2];
  f[0] = 4;
  return f[1];
}
EOF
ln -s foo.c foo.cpp
gcc foo.c -Wall -O2
g++ foo.cpp -Wall -O2

In C, the warning is "foo.c:2: warning: 'f[1]' is used uninitialized in this
function"
In C++, the warning is "foo.cpp:2: warning: 'f$1' is used uninitialized in this
function"

Minor bug with perhaps a minor fix.
