                    -fstrict-overflow produces wrong code (fpe)
           Product: gcc
           Version: 5.3.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

After rebuild gmp (6.1.0 now) with -floop-nest-optimize over -O2 or -O1
-fstrict-overflow - gmp broken (gcc floating point exception). IMHO same was
time ago with older versions of all. amd64. Same with +- asm & pgo.
