[Bug rtl-optimization/45652] New: [4.6 Regression] gcc.dg/compat/scalar-by-value-3 FAILs with -O2 -fselective-scheduling2

[zsojka at seznam dot cz]

I don't know how much is this related to PR43494. This one is failing with
-fselective-scheduling2 and with different target. Also it started failing just
few revisions ago.

Compiler output:
$ cd gcc/testsuite/gcc.dg/compat
$ gcc -O2 -fselective-scheduling2 scalar-by-value-3_main.c
scalar-by-value-3_x.c scalar-by-value-3_y.c
$ ./a.out 
Aborted

(fails with -O[23s])

Tested revisions:
r164228 - fail
r163636 - fail
r161659 - OK

Reduced testcase to follow.
