Because we (as in the Project) have not validated that all of the code=20 compiles correctly in high-parallelism situations. We frequently find=20 areas that do not have proper ordering set and you get odd compile errors.= =20 As machines get faster, we find more races. In general, compilation with non-standard CFLAGS and COPTFLAGS is not=20 supported. If it doesn't work, remove the options from your make.conf and= =20 re-attempt your build. The code should build with the default CFLAGS and=20 no -j set. If you can identify and provide a patch for areas that don't work properly= =20 at -j, we'll happily accept them, but if you have problems, you're on your= =20 own. We can't possibly test every possible permutation of CFLAGS and -j;=20 we don't have the resources. --=20 Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org --0-1935939020-1149893197=:60598--
