            Bug ID: 36473
           Summary: Scanning fis-gtm produces multiple cores
           Product: clang
           Version: 4.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
          Assignee: dcoughlin at apple.com
          Reporter: Amul.Shah at fisglobal.com
                CC: llvm-bugs at lists.llvm.org

I am using the Clang SCA to analyze the source code of FIS GT.M (fis-gtm.com)
and have run into a number of failures that result in analyzer core dumps. I
understand that the bug report in this email will need to be re-entered into
the bug tracker, but since there will be some turn-around time between getting
access to the bug tracker and me needing to write the bug report, I thought it
would prudent to type up the report now.

Source Code:

Steps to reproduce:
1. Download sources and install dependencies listed in the README (on
Debian/Ubuntu installing fis-gtm will install all of the dependencies)
2. Execute the following from the source directory
mkdir build && cd build
export PATH "${PATH}:/usr/libexec"
set utflocale = `locale -a | gawk
setenv LANG C
setenv LC_ALL "${utflocale}"

setenv CCC_CC clang
setenv CCC_CXX clang++
set ccc_analyzer=`which ccc-analyzer`

echo "Building in ${PWD}"
scan-build --status-bugs -analyze-headers -stats -disable-checker
deadcode.DeadStores -analyzer-config stable-report-filename=true -o ${PWD} make
-j 8
