[Bug debug/42977] New: "-fcompare-debug failure" with "-O2 -finline-functions -fomit-frame-pointer -ftracer -fsched2-use-superblocks -fPIC"

[zsojka at seznam dot cz]

Command line:
g++ -O2 -finline-functions -fomit-frame-pointer -ftracer
-fsched2-use-superblocks -fPIC -fcompare-debug -c testcase.cpp -m32
(x86_64 needs -m32)

Tested revisions:
r156515 - crash
r156472 - crash
r156468 - crash
r156467 - OK

Testcase before reducing was crashing stopped crashing in r156468. Some
partially-reduced testcases were crashing in different revisions. It can happen
this will stop crashing in future revisions because it will hide again.
