I tried to compile openssl with head.
I found a problem with (reduced case):
#include <stdio.h>
static void func(char *(*md)(char *md))
{
(*md)("test");
}
static char *a(char *a)
{
printf("%s\n", a);
return a;
}
int main(void)
{
func(a);
}
I could fix this with attached patch.
Probably not the best fix 🙂
