Description of problem:
dmraid fails to build with rawhide gcc versions, both with gcc-10.1.1-2.fc33 and with gcc-10.2.1-1.fc33.
The exact same sources did build fine on s390x with 10.0.1-0.13.fc33. So it seems this is a regression introduced in gcc 10.1.x .
I've tried disabling lto as well as disabling annobin, neither helps.
Here is the error with annobin enabled (the default) :

I get the exact same error when building without annobin.
Ah, reproduced now, doesn't seem to be specific to s390x in any way.
Testcase for -O2:
void bar (int, void *) __attribute__((__access__(__read_only__, 2)));
void
foo (void *c)
{
struct S { void (*fn) (); } f = { bar };
f.fn (0, c);
}
