The 'conftest1.c' and 'conftest2.c' ./configure testcases

I'm trying to analyze a certain project [1] with the clang-analyzer. But at a
certain step [2] during 'scan-build ./configure', the command appears to loop.
This step is trying to compile 2 small C testcases, 'conftest1.c' and
'conftest2.c' (which Ive included in the attachment), and the executed
commandline is this :

/bin/sh ./libtool --mode=compile /usr/local/bin/../libexec/ccc-analyzer
conftest1.c -c -o conftest1.lo

Running this on the command line gives me endless lines of this :

Waiting for -c.o.lock to be removed
Waiting for -c.o.lock to be removed
Waiting for -c.o.lock to be removed

If I just run './configure' without scan-build, the configure finishes quite
fast and as expected. I'm running a recent svn version (r252789) of
llvm/clang/scan-build on Fedora 23.
