It gots much worse, with --enable-checking=all in combination with --enable-build-poststage1-with-cxx (the default, if c++ is built, and --enable-bootstrap is asserted). In fact, a build started last night on fast server hardware has yet to finish. This particular compilation (insn-emit.c) has been running for 5.5 hours. Typically, a full bootstrap (with minimal checks) would finish in much less than 30 minutes on this server. Has anyone tried a full bootstrap with c,c++ and --enable-checking=all? Were you successful? How long did it take to complete? I haven't looked into this in detail, however, I wonder that if the C++ compiler is used for final build, whether the build/make will honor CFLAGS or CXXFLAGS? Presumably the latter (CXXFLAGS). This seems like a potentially surprising side effect, if true.
