Full support was only added with GCC 5. I added a patch to gcc48 to properly diagnose missing -fsanitize=address. Can you verify it works after the building in devel:gcc has completed? -- You are receiving this mail because: You are on the CC list for the bug.

I cannot make it to build with the devel:gcc gcc.

I even removed the Leap repo but OBS still installs 22.2 revision of the compiler while devel:gcc has 174.1.

Installing the compiler in SLE does not give working environment because SLE does not have the libraries for building the package.

Still it can be tested much easier:

touch test.c gcc -fsanitize=address test.c test.c:1:0: warning: -fsanitize=address not supported for this target [enabled by default] /usr/lib64/gcc/powerpc64le-suse-linux/4.8/../../../../powerpc64le-suse-linux/ bin/ld: cannot find libasan_preinit.o: No such file or directory /usr/lib64/gcc/powerpc64le-suse-linux/4.8/../../../../powerpc64le-suse-linux/ bin/ld: cannot find -lasan collect2: error: ld returned 1 exit status gcc --version gcc (SUSE Linux) 4.8.5 rpm -qi gcc48 Name : gcc48 Version : 4.8.5 Release : 174.1

meaning it's still broken unless I am missing a library/plugin which does not have a strict dependency so would not be pulled with gcc.

Hm? It now works as expected (same behavior as on arm, now including the warning). -fsanitize=address is _not_ supported on ppc64le with GCC 4.8. Were you expecting it to work? -- You are receiving this mail because: You are on the CC list for the bug.
