Bug #: 50956
Summary: -Wcast-qual does not work
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: joerg.rich...@pdv-fs.de
-Wcast-qual seems to be broken since at least GCC 4.1.1.
cat > t.cc <<EOF
int main( int, char** )
{
void* p = (void*)"txt";
return 0;
}
EOF
g++ -o /dev/null -c t.cc -Wcast-qual # no warning
GCC 3.4.5 gives a warning:
t.cc: In function `int main(int, char**)':
t.cc:3: warning: cast from `const char*' to `void*' discards qualifiers from
pointer target type
