<div>Hi all, after building the svn 3.1 version ussing the DEBUG target I have been able to compile withoit crashes, I'll continue uptating the bug database.</div>
<div> </div>
<div>As I coment in the bug this kind of bug usually is caused by uninitialized memory or bad stl use, I'll build a RELEASE target with debug information so I can try to find the crash.</div>

<div>Hello, after some test my latest clang+llvm build "almsot worked" but I was experiencinf some crashes.</div>
<div> </div>
<div>I found the experimental win32 binry on the repo, so I donwnloaded and tested it on other machine and that version works fine, so I got mu svn pointing to the llvn and clang 31 release final tag and recompiled it.</div>
<div> </div>
<div>That improved my build (running on w7 profesional 64bits) but my clang still crashes on some files that with the provided 32bit binary work, so how can try to find/fix it...</div>
