Created an attachment (id=20336)
 -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20336action=view)
testcase with inlined f()

Even when the f() is declared as

static inline __attribute__((always_inline))
double f(struct s1 *a, struct s2 *b)

the testcase still fails with:
$ gcc -fschedule-insns -fstrict-aliasing pr43495-2.c  ./a.out
Aborted

Testcase from comment #5 fails at x86_64-linux, trunk r153685, r158095.
It doesn't fail in the 4.4 branch.

The test is bogus and does not agree with how GCC interprets type-based
aliasing rules.  Thus it invokes undefined behavior (dependent on whether
we inline or not).

OK, I'll modify the testcase to ensure function f() gets inlined.
