            Bug ID: 69839
           Summary: cross-compiling programs w/-fsanitize=address fails:
                    ld: warning: libstdc++.so.6, needed by libasan.so, not
                    found (try using -rpath or -rpath-link)
           Product: gcc
           Version: 4.9.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: joakim.tjernlund at infinera dot com
  Target Milestone: ---

Using gcc 4.9.3 I can using the native gcc build ASAN:
# > gcc -fsanitize=address mmap.c
# >

However, using a ppc32 cross gcc build with crossdev I cannot:
# > powerpc-g2.20-linux-gnu-gcc -fsanitize=address mmap.c
/usr/libexec/gcc/powerpc-g2.20-linux-gnu/ld: warning: libstdc++.so.6, needed by
/usr/lib/gcc/powerpc-g2.20-linux-gnu/4.9.3/libasan.so, not found (try using
-rpath or -rpath-link)
# >

Adding -lstdc++ works though:
# > powerpc-g2.20-linux-gnu-gcc -fsanitize=address mmap.c -lstdc++
