See this message and followups: http://gcc.gnu.org/ml/gcc/2006-08/msg00398.html Here are the specifics that I have: 20060724, make check-target-libstdc++ 1145.687u 137.804s 23:13.98 92.0% 0+0k 0+0io 23pf+0w 20060822, make check-target-libstdc++ 2624.876u 247.539s 55:42.82 85.9% 0+0k 0+0io 45pf+0w Ouch. In that time, there have been some additions in the libstdc++ testsuite, however it did not double in size. I've been trying to compile mainline libstdc++ with 4.1.1 g++ to see if I can pin down the issue to a particular component but there are a lot of incompatible changes, so comparing directly is difficult to impossible. -- Summary: massive C++ compile time slowdown Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: major Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: bkoz at gcc dot gnu dot org GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28871
