I took that patch and applied it to the gcc sources, but I still see the error on ppc: ... [bergner@makalu-lp1 asan]$ LD_LIBRARY_PATH=:/home/bergner/gcc/build/gcc-fsf-mainline-asan-debug-3/gcc:/home/bergner/gcc/build/gcc-fsf-mainline-asan-debug-3/gcc/32:/home/bergner/gcc/build/gcc-fsf-mainline-asan-debug-3/powerpc64-linux/32/libsanitizer/asan/.libs::/home/bergner/gcc/build/gcc-fsf-mainline-asan-debug-3/gcc:/home/bergner/gcc/build/gcc-fsf-mainline-asan-debug-3/gcc/32:/home/bergner/gcc/build/gcc-fsf-mainline-asan-debug-3/powerpc64-linux/32/libsanitizer/asan/.libs: ldd ./asan-interface-1.exe linux-vdso32.so.1 => (0x00100000) libm.so.6 => /lib/power8/libm.so.6 (0x0ff00000) libasan.so.1 => /home/bergner/gcc/build/gcc-fsf-mainline-asan-debug-3/powerpc64-linux/32/libsanitizer/asan/.libs/libasan.so.1 (0x0f930000)
Now check indeed seems to be useful: libasan should be the first library in the list when -fsanitize=address flag is present. Are compiler specs for Power somehow special?
