<body class='hmmessage'><div dir='ltr'>Hi,
Actually, I don't know what version of clang is that, because I just followed this in the cloud9 (http://cloud9.epfl.ch/setting-up)
$ cd $CLOUD9_ROOT
$ gclient config --name src git+https://github.com/dslab-epfl/cloud9-depot.git
$ gclient sync
so when I run the gclient sync it will download LLVM+clang and build it. And I don't have any bug report that prdouce by clang. But when I run the make command again inside the klee folder I got the same
problem

What version of clang are you using? Clang should generate a crash report with preprocessed file and invocation script that reproduces the bug, do you have this?

Hi All,
I am building and installing the cloud9 symbolic execution engine in VMware, Ubuntu 12.04 machine. And in the middle of compiling process I got error like this

Please help me, trying this for couple of days but no luck..
Thank-you
