Bug ID: 82305
   Summary: gcc.c-torture/execute/2822-1.c fails on x86_64
Cygwin
   Product: gcc
   Version: 7.2.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c
  Assignee: unassigned at gcc dot gnu.org
  Reporter: pen7cmc at yahoo dot com
  Target Milestone: ---

CYGWIN_NT-10.0 2.9.0(0.318/5/3) 2017-09-12 10:18 x86_64 Cygwin

The --with-isl=/usr/local below is because ISL 0.14 is the version Cygwin's
setup-x86_64.exe program downloads, below what gcc 7.2.0 needs.  I installed
ISL 0.18 in /usr/local.

../configure --prefix=/opt/etsf --with-local-prefix=/opt/etsf/usr/local
--enable-languages=c,c++,fortran --with-isl=/usr/local
make -j 2
make check
