nm --version -> GNU nm (GNU Binutils; openSUSE 11.4) 2.21 Output from "nm -g" does not include symbols of type "u" = "unique <em>global</em> symbol". Also, related documentation bug for nm. The man page says, regarding the symbol type: "If lowercase, the symbol is local; if uppercase, the symbol is global (external)." That sentence from the documentation appears to have been previously violated by the "v" and "w", and now again by "u", except the latter isn't treated as global by the -g flag.

Hi Kim, Thanks for reporting this bug. I have checked in a patch to fix it, as well as a correction to the documentation to explain that not all lowercase letters refer to local symbols. I have also extended the binutils testsuite to cover this scenario, so the problem should not reoccur. Cheers Nick
