Symbols nsObsoleteAString::sCanonicalVTable and
nsObsoleteACString::sCanonicalVTable are in two files simultaneously.

$ nm -C /usr/local/lib/firefox/firefox-bin|egrep 'nsObsoleteAC*String::sCanonicalVTable'
00000000002348f8 B nsObsoleteAString::sCanonicalVTable
00000000002348f0 B nsObsoleteACString::sCanonicalVTable

$ nm -C /usr/local/lib/firefox/libxpcom_core.so|egrep 'nsObsoleteAC*String::sCanonicalVTable'
0000000000268e00 B nsObsoleteAString::sCanonicalVTable
0000000000268e08 B nsObsoleteACString::sCanonicalVTable

This is correct? If not, where is the bug: gcc, binutils or mozilla?
