In C++, different lists of exported symbols based on the phase of moon are completely normal, for example when template instantiation is involved. So more details would be welcome. I think that dpkg-gensymbols is misleading in that it treats all symbols exported as the same, not differentiating where they come from. Yes, you do have the option to mark a symbol as optional, however marking a symbol as coming from another library (libstdc++, Webkit:Core) would help too, but would require some work by the package maintainer too. Whether a template operator or another template from another library ends up as an exported symbol depends on the toolchain (different compiler/linker, different version, different optimization level), and that should not be encoded in the symbols files.
