Package: gcc-6 Version: 6.4.0-1 Severity: important Dear Maintainer,
building autotools packages with address sanitizer currently breaks with gcc-6 and gcc-7. gcc-5 is not effected. This breaks quality checking and fuzzing with ASAN enabled. Using LD_PRELOAD to load libasan first doesn't change anything. This doesn't help either (in case this is a ASLR problem with the kernel): echo 0 >/proc/sys/kernel/randomize_va_space $ CC=gcc-6 CFLAGS="-g -fsanitize=address -fno-omit-frame-pointer" ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking for gcc... gcc-6 checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... configure: error: in `/usr/oms/src/libpsl': configure: error: cannot run C compiled programs.
