Flexible array bug?
Hi,
I have run into a strange problem with the Sun Studio 11 compiler and flexible arrays.
The C99 code below contains a struct, "flex_struct", which has a flexible array member.
When I compile the file "flex_problem.c", see below, I get an error message saying that "const_func"
is redeclared. (Note that the compiler does not complain about the non-const version "func".)
Is this a known problem?
// file: flex_problem.h
struct flex_struct;
void func(struct flex_struct *sp);
void const_func(const struct flex_struct *csp);
// end of file flex_problem.h
// file: flex_problem.c
#include "flex_problem.h"
struct flex_struct {
int i;
int iv[];
};
void
func(struct flex_struct *p)
{
}
void
const_func(const struct flex_struct *cp)
{
}
// end of file flex_problem.c
