So I updated my FreeBSD machine to 9.1-RELEASE in the hope of getting
past the ctfconvert problem that causes a build of 10-CURRENT to say:

while compiling every kernel source file. Then I checked out head as
of 245422 into a different partition and tried "make buildworld" (ran
okay) and "make buildkernel" (failed with the same error as before).
Do I have to build an early version of head before I can build the
current version of head? -- George Mitchell
FWIW;
While looking at NetBSD's Dtrace enhancements I found that
this is caused[1] by a known bug in gcc. It was fixed in our base gcc
recently and MFC'd.
Last time I looked, upstream gcc hasn't fixed it, and I am trying
to get the illumos guys to review the NetBSD workaround before
we adopt it.
No, this is most likely not a gcc issue. I am fairly certain it is
fixed by commit r239872 to libdwarf, but as I noted in another reply,
this fix did not make it into 9.1-RELEASE.
