Synopsis: Taking address of casted value gives error
State-Changed-From-To: open->closed

State-Changed-Why:
Not a bug - the two are not equivalent; in one you're taking the address of an lvalue, in the other you're not.

Ark Linux Dockyard (Linux 2.4.20, glibc 2.3.2)
>Description:
The following simple code:
int test(void **tmp) { }
int main(int argc, char **argv)
{
char *a="Test";
test(&(void*)a);
}
gives:
test.c: In function `main':
test.c:6: error: invalid lvalue in unary `&'
This slightly longer, but equivalent variant works:
int test(void **tmp) { }
int main(int argc, char **argv)
{
char *a="Test";
void *b=(void*)a;
test(&b);
}
Problem occurs with both the C and C++ front ends.
