I don't. Using -fno-rtti to build a package that many other packages may link to seems wrong. It's a typical case of premature optimization. And it hurts, as is obviuous here. That flags cripples the c++ compiler to a (non-standard) subset of the language, in non-obvious ways: beside typeid, dynamic_cast and exception handling may work differently (if at all). The first is typically used in libraries like boost::variant, which are useful in applications communicating with a database. As Marcel already noted: To disable RTTI saves some kilobytes of executable size. (Code size and working set size is unaffected.) So it buys really nothing, considering that other build flags used routinely in Arch (-D_FORTIFY_SOURCE=2 or -fstack-protector-strong) are much more costly. Regards
