GCC : undefined reference to "__asan_init_v1" - gcc

Question

I want to compile my C99 project with the flag -fsanitize=address. I need to use CMake and to compile with gcc on a Centos 7 distribution.
I currently have gcc 7.3.1 and cmake 3.13.4.
I added the -fsanitize=address flag in the compilation flags list and in the linker, but it still fails to compile with the following error:

Your toolchain is somewhat confused about which version of GCC it is and
the linkage failure is one consequence of that confusion.
You tell us you are using GCC 7.3.1, but the first of the unresolved references to __asan_init_v1:
/usr/lib/gcc/x86_64-redhat-linux/4.8.5/libasan_preinit.o:(.preinit_array+0x0) : undefined reference to « __asan_init_v1
shows that the gcc that invoked the linkage with -fsanitize=address linked the address santitizer initialization code
from your installation of GCC 4.8.5.
In GCC 7, the file libasan_preinit.o makes no references to __asan_init_v1, as seen on
the laptop I'm working on just now:
$ nm /usr/lib/gcc/x86_64-linux-gnu/7/libasan_preinit.o
U __asan_init
0000000000000000 D __local_asan_preinit
It calls __asan_init, which is indeed defined in the toolchain's libasan:
$ nm -D /usr/lib/gcc/x86_64-linux-gnu/7/libasan.so | grep __asan_init
00000000000ecdb0 T __asan_init
On the other hand, in GCC 4.8.5, libasan did not define the function __asan_init
and did define __asan_init_v1:
:~/Downloads/gcc-4.8.5$ grep -r '__asan_init_v'
gcc/ChangeLog: * sanitizer.def: Rename __asan_init to __asan_init_v1.
gcc/sanitizer.def:DEF_SANITIZER_BUILTIN(BUILT_IN_ASAN_INIT, "__asan_init_v1",
libsanitizer/asan/asan_interface_internal.h: void __asan_init_v1() SANITIZER_INTERFACE_ATTRIBUTE;
libsanitizer/asan/asan_interface_internal.h: #define __asan_init __asan_init_v1
There, __asan_init was just an internal #define aliasing the real function __asan_init_v1, as
per libsanitizer/asan/asan_interface_internal.h, but in that file in GCC 7
// This function should be called at the very beginning of the process,
// before any instrumented code is executed and before any call to malloc.
SANITIZER_INTERFACE_ATTRIBUTE void __asan_init();
it is a real function, as reported by nm.
So the thrust of the evidence is that you are linking against the libasan of GCC 7.3.1
but also linking the library initialization code of GCC 4.8.5. I have no visibility of
how you've landed in this GCC version mash-up - could be a packaging bug, for all I know - but
you'll have to fix that to solve these linkage failures.
