--- Comment #16 from Stupachenko Evgeny <evstupac at gmail dot com> ---
I can't attach spec2000 benchmarks sources.
The loop is in "longest_match" function in 164.gzip.
Options to reproduce: "-Ofast -funroll-loops -flto -march=corei7 -m32 -fPIE
-pie" (-march=slm reproduce the issue as well).
I'm checking if the issue reproduced without "-flto".
