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.
If you meant to cross compile, use `--host'.
