I doubt it. If anything, C++, but even that doesn't seem likely. The vast majority of languages seem to be self-hosted. A good portion compilers or interpreters in C or C++ probably use (F)lex and Yacc/Bison so even saying C or C++ are the most popular choice (but not necessarily the majority) sounds like a stretch.
