Anyone else seeing this?

It builds here (Linux x86_64), I use the following configure line:
../llvm-gcc4.2/configure
--prefix=/home/edwin/llvm-svn/obj42/../install --program-prefix=llvm-
--enable-llvm=/home/edwin/llvm-svn/llvm/ --disable-multilib
--enable-checking=release --enable-languages=c,c++
What is yours?
Best regards,

Ciao,
Duncan.
I can't get it to not fail: even if I use the flags that
worked for you it fails for me... Maybe the difference
is in how llvm was built? I configured using only default
values, i.e. without passing any parameters to configure.
Ciao,
Duncan.
For llvm:
./configure --enable-targets=x86,cbe,cpp --enable-optimized
One thing I noticed is that sometimes the Debug directory was picked
from llvm while building llvm-gcc, which contained an out-of-date build.
I no longer have a Debug directory though.
I just tried to build in a clean object directory, and it failed with
same error message.
Perhaps some files remained from an old build, and didn't get removed on
a make clean?
This means that I don't have a working llvm-gcc with TOT either.

I get the same thing on x86-32.

HAVE_STDLIB_H is not defined, which causes a 'char* malloc()' definition
in cplus-dem.c.
From config.log:
configure:8421: checking for stdlib.h

Did you open a bug for this?

Hello, Everyone
Did you open a bug for this?
I backed out few recent llvm-gcc commits and this effectively restored the build. See llvm-commits ML for full explanation of the problems (actually, there were 2).
This means that I don't have a working llvm-gcc with TOT either.
I get the same thing on x86-32.
Ciao,
Duncan.

This is caused by -Wformat-security, which is enabled by default

This was likely introduced by revision 55675
Here is a patch that works for me in a clean directory (it probably
needs an LLVM local marker), does it work for you?
