Seems to be specific to gcc-6, the file is available in libgcc-4.9-dev, libgcc-5-dev, and gcc-snapshot (7.0.0).

Bug#836848: libasan3: AddressSanitizer breaks when LD_PRELOAD is defined
Package: libasan3 Version: 6.2.0-3 Severity: normal When LD_PRELOAD is defined (which can be a consequence of gtk3-nocsd being installed and the user being in an X11 session), I get: cventin:~> gcc -fsanitize=address t.c cventin:~> ./a.out ==22051==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. Something should be done. This was very confusing at first, because the problem first came here when I ran a configure script which was working a few days ago (after investigation, it is now clear that the reason was that it wasn't under a X11 session a few days ago), and just saw: checking whether we are cross compiling... configure: error: in `/home/vlefevre/tmp/mpfr-old': configure: error: cannot run C compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details I could see the error message, but the reason wasn't clear yet (I initially thought of a regression after a recent upgrade). So, I think that if possible, having LD_PRELOAD already set shouldn't affect ASan. Shouldn't -static-libasan be the default, for instance? If this is not possible, various things should be clarified: 1. The error message should be more informative, e.g. when LD_PRELOAD is set, say that LD_PRELOAD is set but ASan runtime does not appear in LD_PRELOAD or does not come first. 2. The gcc(1) man page does not mention LD_PRELOAD at all. Ditto for the GCC manual. 3. How to find the right ASan runtime *automatically* should also be documented. -- 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 4.7.0-1-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 libasan3 depends on: ii gcc-6-base 6.2.0-3 ii libc6 2.24-2 ii libgcc1 1:6.2.0-3 ii libstdc++6 6.2.0-3 libasan3 recommends no packages. libasan3 suggests no packages. -- no debconf information

Package: libasan3 Version: 6.2.0-3 Severity: normal While -fsanitize=address -static-libasan works on a simple .c file, it no longer works in a more complex case.
