Thank you, very well. Can you (or somebody else who sees the failure with -jN, N>1) try a bootstrap on x86_64-apple-darwin10 with non-parallel make from a clean directory? If that fails, that would be a pretty clear indication that this bug has nothing to do with make parallelism. (There are lots of other reasons why bootstrap comparisons can fail, some of which are quite system-dependent, so a builds on darwin9 and on darwin10 may not both expose the issue.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43170
