Subject: [Bug c++/35711]  New: bad text in -Wcast-qual warning (forgets volatile)
Date: Wed, 26 Mar 2008 20:14:00 -0000	[thread overview]
Message-ID: <bug-35711-1186@http.gcc.gnu.org/bugzilla/> (raw)

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 837 bytes --]

The text of the warning below is incorrect and misleading -- the cast
actually casts away the volatile qualifier, not constness. The warning
is misleading when the type of the source is both const and volatile
qualified.

$ cat t.cpp && g++ -c -Wcast-qual t.cpp
int* foo (volatile int *p)
{
    return (int*)p;
}
t.cpp: In function ‘int* foo(volatile int*)’:
t.cpp:3: warning: cast from type ‘volatile int*’ to type ‘int*’ casts away
constness
