Was it > changed lately? Debian gcc-4.6 4.6.3-8 does place the pointer in .ctors, but ld of binutils 2.22-6.1 then moves it to .init_array. Perhaps the same happens in your test with 4.6.3-1ubuntu5. Mentioned in <http://sources.redhat.com/bugzilla/show_bug.cgi?id=12910>. Debian gcc-4.7 4.7.1-2 places the pointer directly in .init_array. Implemented in <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46770>.
