Subject: [Bug c++/41847]  New: warning: array subscript is above array bounds
Date: Tue, 27 Oct 2009 14:46:00 -0000	[thread overview]
Message-ID: <bug-41847-8961@http.gcc.gnu.org/bugzilla/> (raw)

#  gcc -Wall -O2 -c demo.cxx
demo.cxx: In function ‘void isInvertible()’:
demo.cxx:12: warning: array subscript is above array bounds

gcc --version
gcc (GCC) 4.4.2 20091019 (Red Hat 4.4.2-5)

I've the same results with...
gcc (GCC) 4.4.2 20091019 (Red Hat 4.4.2-5) (gcc-4.4.2-5.el6.s390x)
gcc (GCC) 4.4.1 20090725 (Red Hat 4.4.1-3) (gcc-4.4.1-3.s390x)
gcc (GCC) 4.4.0 20090506 (Red Hat 4.4.0-4) (gcc-4.4.0-4.s390x)

Possibly a duplicate of #35392
so its not a very recent thing.

I only get this warning (and related runtime failure) with s390x. Equivalent
x86_64/x86/ppc/ppc64/arm gcc's appear fine
