            Bug ID: 23048
           Summary: scan-build fails to build with
                    -fstack-protector-strong
           Product: clang
           Version: 3.6
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
          Assignee: kremenek at apple.com
          Reporter: jhi at iki.fi
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

I tried to use scan-build (OS X; installed via macport), for the latest Perl
source code (hence the -Dusedevel below), but probably works for e.g. Perl
5.21.10 snapshot from http://search.cpan.org/~shay/perl-5.21.10/

sh Configure -des -Dusedevel -Dcc=clang-mp-3.6

scan-build-mp-3.6 make

/opt/local/libexec/llvm-3.6/libexec/scan-build/ccc-analyzer

because it contains no reports.
scan-build: No bugs found.

The -fstack-protector-strong gets added automatically by Configure.  (Note: it
really is Configure, not configure.)  I got past the error by

perl -pi -e 's/-fstack-protector-strong//' config.sh

and re-issuing the scan-build.
