GCC 5.0 is near release, and Fedora has started building packages with
it. The ECL build is failing because the stack direction code in
src/aclocal.m4 has started returning wrong values. I don't know why.
But I do know that replacing the test code with this returns the
correct answer:
#include <stddef.h>
#include <stdlib.h>
ptrdiff_t f2(const char *d) {
char c[2];
return c-d;
}
ptrdiff_t f1(const char *d) {
char c[2];
return c+1-d;
}
typedef ptrdiff_t (*f_ptr)(const char *);
f_ptr f[2] = { f1, f2 };
ptrdiff_t signo() {
char d[1];
return f[rand() & 1](d);
}
int main() {
if (signo() > 0)
return 1;
else
return 0;
}
