Well, new symbols shouldn't be a problem (removed symbols would be, if other packages expect them). Based on https://github.com/conda-forge/snappy-feedstock/issues/35 what apparently happened is that the snappy developers released 1.2.0 but forgot to update the library soname even though they changed function signatures. The lookup of that symbol _ZN6snappy11RawCompressEPKcmPcPm which is the mangled version of snappy::RawCompress(char const*, unsigned long, char*, unsigned long*) fails because the new version only has a (mangled) symbol for snappy::RawCompress(char const*, unsigned long, char*, unsigned long*, snappy::CompressionOptions) That's a bug in snappy, and it will affect things other than qtwebengine too… You should probably ask the Gentoo developers to revert to the previous version or patch it. There's probably a way to ask the Gentoo package manager to downgrade the package, too.
