[Bug debug/43516] New: "-fcompare-debug failure" at -O2

[zsojka at seznam dot cz]

Command line:
gcc -O2 -fcompare-debug testcase.c

Tested revisions:
r157677 - fail (i686)
r157675 - OK (x86_64)
but after reducing, one of testcases started failing at x86_64

further reducing is hard, and this could be a dup of pr42977
