--- Comment #1 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
icpc and g++:

markus@x4 /tmp % icpc -c b.cc && nm -C b.o
                 U abort
                 U __gxx_personality_v0
0000000000000000 T bar()
0000000000000000 V void foo<int>(char (*) [sizeof (((anonymous
namespace)::A)((int)(0)))])::cnt

markus@x4 /tmp % g++ -c b.cc && nm -C b.o
                 U abort
0000000000000000 T bar()
0000000000000000 W void foo<int>(char (*) [sizeof (((anonymous
namespace)::A)((int)(0)))])
0000000000000000 u void foo<int>(char (*) [sizeof (((anonymous
namespace)::A)((int)(0)))])::cnt

clang mangles differently and therefore avoids the issue:

markus@x4 /tmp % clang++ -c b.cc && nm -C b.o
                 U abort
0000000000000000 T bar()
0000000000000000 W void foo<int>(char (*) [2])
0000000000000000 V void foo<int>(char (*) [2])::cnt
