[Bug c/33901] New: assumes target of a const pointer is read-only

[rmh at gcc dot gnu dot org]

Given the following code:

main ()
{
  const char *foo = 0;
  *foo = 0;
}

gcc will refuse to compile it with:

$ echo "main () { const char *foo = 0; *foo = 0; }" | gcc -x c -c - -o
/dev/null
<stdin>: In function ‘main’:
<stdin>:1: error: assignment of read-only location

Sure, foo is read-only, but *foo is just a memory location; one should be able
to write to it.
