Bug ID: 70064
Summary: wrong code with custom flags and quite big testcase @
i686
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: zsojka at seznam dot cz
Target Milestone: ---
Target: i686-pc-linux-gnu

autoreduced testcase
The testcase is likely very fragile due to the set of compiler flags and quite
big testcase itself. Neither seems to be easily reducible.
