Not sure if this is the right place to report, but it was suggested that I file
a bug at IRC; I was not able to google up a similar issue either.

I was compiling llvm+clang from SVN (nested checkout as per
http://clang.llvm.org/get_started.html) with default configure arguments (both
optimized and debug builds) using g++ 4.4 and g++ 4.5. After make && make
install, any program (clang, llvmc, ...) from the llvm suite is killed
immediately at startup:

$ llvmc
zsh: killed     llvmc

$ strace llvmc
execve("/usr/local/bin/llvmc", ["/usr/local/bin/llvmc"], [/* 48 vars */]
<unfinished ...>
+++ killed by SIGKILL +++
zsh: killed     strace llvmc

$ gdb /usr/local/bin/llvmc

Executable arch matches the system (`uname -m` = x86_64):

$ file /usr/local/bin/llvmc
/usr/local/bin/llvmc: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped

I am running Ubuntu 10.04 at amd64, exact compiler & linker versions are:

g++-4.4 (Ubuntu 4.4.3-4ubuntu5) 4.4.3
g++ (Ubuntu 4.5.0-2ubuntu1~ppa2) 4.5.1 20100419 (prerelease)
GNU gold (GNU Binutils for Ubuntu 2.20.51-system.20100418) 1.9

If you can suggest further ways to diagnose this problem, let me know. I can
provide as much information as needed.
