[LLVMdev] changes to raw_fd_ostream

I'm getting seemingly odd SegFaults  when writing out using a
raw_fd_ostream in the current trunk (last version worked, believe it was
153818, or similar). Again, nothing in the release notes... should I be
scanning the svn log?

For example, I have something like:

raw_fd_ostream fout("out.txt", errorStr="");
fout<<"Hello World, how are you!"\n";

and it'll write out to the file, "Hello Wor" and then seg fault without

Sadly, this only happens for certain C code, any idea why this might be

Also, during build I get a lot of these warnings:llvm/ADT/DenseMap.h: In
copy constructor ‘llvm::DenseMap<KeyT, ValueT, KeyInfoT>::DenseMap(const
llvm::DenseMap<KeyT, ValueT, KeyInfoT>&) [with KeyT = unsigned int, ValueT
= llvm::PointerAlignElem, KeyInfoT = llvm::DenseMapInfo<unsigned int>]’:

I'm guessing I messed up when updating somehow? I just used gmake update.
