I'm trying to build the 2.5 prerelease on my MacBook, and I'm getting
a bus error in tblgen:
$ rm -r * && ../src/configure --prefix=`pwd`/../install && make -j1

Looking through the code, I don't see anything wrong. Here's a bunch
of maybe-relevant information, but let me know if I should send
anything else.

Oddly, I can't look at the contents of an opt<string> until I run
(gdb) add-symbol-file
/Users/jyasskin/src/llvm-2.5/obj/lib/Support/Debug/CommandLine.o
Then I get the following at the crash:
(gdb) f 3
(gdb) p O

This happens both with and without the binaries from
llvm-gcc4.2-2.5-x86-darwin9.tar.gz symlinked into my PATH. It also
happens in both release and debug builds.
