Hi,
Ouch, this doesn't look good. I was able to write a similar two
line example:
const int foo[2] = {1,1};
((int*)foo)[0] = 0;
which was accepted with -Wcast-qual by Apple-g++ 4.0.0, and FSF g+
+-4.0.2.
g++-3.3 rejects it as we'd expect. (and I depend on warnings to
catch
such evil in my code (-Werror)!) Consider filing a report to
http://gcc.gnu.org/bugzilla/?
/usr/bin/gcc-3.3 -c main.cpp -Wcast-qual
returns
main.cpp: In function `int main(int, char**)':
main.cpp:8: warning: cast from `const char*' to `char*' discards
qualifiers
from pointer target type
gcc -c main.cpp -Wcast-qual
returns nothing,
I'm talking about 10.4.3 and XCode 2.1 so default compiler is gcc
4.0.0
