Non-constant initializer error; compiler bug?

Question

The following code snippet demonstrates the issue:
typedef struct {
char *p;
} S1;
int main()
char a;
S1 s = { &a };
hadron:~/src/misc> cc -V junk.c
cc: Sun WorkShop 6 update 1 C 5.2 2000/09/11
acomp: Sun WorkShop 6 update 1 C 5.2 2000/09/11
"junk.c", line 8: non-constant initializer: op "U&"
The compiler correctly handles the case where 's' is a simple pointer (eg. char *s = &a).  I don't have a copy of K&R handy but surely the C language allows structure initializers to contain address operators.

Are you compiling with some other option? Does this
error occur every time or randomly?
