Hi!

I'm trying to build llvm cvs head on Ubuntu. make command fails with this
(VERBOSE=1):

Bt leads through standart C++ library calls to the following line (109) in
utils/TableGen/TableGen main() function:

Out = new std::ofstream(OutputFilename.c_str());

As for me the TableGen code seems ok (especially because a lot of people
build llvm everyday). I tried to compile llvm with both gcc-3.4.6 and
gcc-4.0.1 but the same error occurs.  So I think that either glibc version
is buggy or  llvm  is not compatible with the latest version (glibc-2.3.6) I
use. The first case don't seem very reasonable because of what I have
investigated with Google (most projects leading to similar malloc error are
said by its support to be out of date). The latter is not reasonable until
it turns out that everybody working on llvm head use some previous versions
of glibc (a bit possible though).  Probably, some right reason remains I
can't think of (some other lib is not installed/updated?).

Any thoughts  on the issue described will be appreciated. I'll provide any
information needed.

Thanks in advance.

Anton.
