             Bug #: 14963
           Summary: scan-build report errors on stdout and fails to set
                    exit code
           Product: clang
           Version: 3.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: aduret at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


In the following command, scan-build reports an error on stdout (instead of
stderr) and fails to adjust $? to signal the problem.

% scan-build ./configure --prefix ~/usr && scan-build make -j2
scan-build: error: Cannot find an executable 'clang' relative to scan-build. 
Consider using --use-analyzer to pick a version of 'clang' to use for static
analysis.
scan-build: error: Cannot find an executable 'clang' relative to scan-build. 
Consider using --use-analyzer to pick a version of 'clang' to use for static
analysis.
% echo $?
0


I would expect (1) that the error is output on stderr, and (2) that $? is set
to a non-zero value so that the "scan-build make" is not even started.
