Hi everybody,

I'm new with clang as i'm using it for few days only. I did set up llvm and
clang 2.9 and when i used clang command for analyze c++ files it worked
almost correctly (since i had bugs but related to my machine i think).

I took recent versions of llvm and clang on SVN repository.
And now it does not work, and here are the errors i obtain when i attempt an
analysis on a file called "list.cpp":

0  clang     0x0a308fd6
1  clang     0x0a308d63
2            0x0023d400 __kernel_sigreturn + 0
3  clang     0x08d2c54f
llvm::StringRef, clang::InputKind) + 1329
4  clang     0x08d14930
clang::CompilerInstance::ExecuteAction(clang::FrontendAction&) + 758
5  clang     0x08cbbf52
clang::ExecuteCompilerInvocation(clang::CompilerInstance*) + 835
6  clang     0x08cadd45 cc1_main(char const**, char const**, char const*,
void*) + 1014
7  clang     0x08cb7a33 main + 521
8  libc.so.6 0x00764e37 __libc_start_main + 231
9  clang     0x08cad421

--> Anybody can say something about it ? I don't really get what occurs

thank you.
