Bug ID: 25502
Summary: 'scan-build ./configure' loops on building
'conftest1.c/conftest2.c'
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Static Analyzer

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.
