Package: gcc-snapshot Version: 20160603-1 Severity: important Tags: upstream Forwarded: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71433
When compiling GNU MPFR 3.1.4 with CFLAGS="-O2 -Werror=array-bounds" and gcc (Debian 20160603-1) 7.0.0 20160603 (experimental) [trunk revision 237077] I get: get_d.c: In function 'mpfr_get_d': get_d.c:115:24: error: array subscript is above array bounds [-Werror=array-bounds] d = (d + tp[i]) / MP_BASE_AS_DOUBLE; ~~^~~ There was no such problem with gcc (Debian 20160508-1) 7.0.0 20160508 (experimental) [trunk revision 236009] so that's a recent regression. I've also reported the bug upstream. -- System Information: Debian Release: stretch/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.5.0-2-amd64 (SMP w/12 CPU cores) Locale: LANG=POSIX, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages gcc-snapshot depends on: ii binutils 2.26-10 ii libasound2 1.1.0-1 ii libatk1.0-0 2.20.0-1 ii libc6 2.22-10 ii libc6-dev 2.22-10 ii libc6-dev-i386 2.22-10 ii libc6-dev-x32 2.22-10 ii libc6-i386 2.22-10 ii libc6-x32 2.22-10 ii libcairo2 1.14.6-1+b1 ii libecj-java 3.10.1-2 ii libfontconfig1 2.11.0-6.4 ii libfreetype6 2.6.3-3+b1 ii libgdk-pixbuf2.0-0 2.34.0-1 ii libglib2.0-0 2.48.1-1 ii libgmp10 2:6.1.0+dfsg-2 ii libgtk2.0-0 2.24.30-2 ii libice6 2:1.0.9-1+b1 ii libisl15 0.17.1-1 ii libmpc3 1.0.3-1 ii libmpfr4 3.1.4-2 ii libpango-1.0-0 1.40.1-1 ii libpangocairo-1.0-0 1.40.1-1 ii libpangoft2-1.0-0 1.40.1-1 ii libsm6 2:1.2.2-1+b1 ii libxrandr2 2:1.5.0-1 ii libxrender1 1:0.9.9-2 ii libxtst6 2:1.2.2-1+b1 ii python 2.7.11-2 ii zlib1g 1:1.2.8.dfsg-2+b1 gcc-snapshot recommends no packages.
