             Bug #: 12421
           Summary: Error is detected for function defined in header but
                    no report is generated
           Product: clang
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek@apple.com
        ReportedBy: roland@utk.edu
                CC: llvmbugs@cs.uiuc.edu
    Classification: Unclassified


Given:
test.c:
#include "test.h"
int main(){
  return f();
}

test.h:
static int f() {
  int *i=0;
  return *i;
}

gives:
$ scan-build c++-analyzer test.cc
In file included from test.cc:1:
./test.h:3:10: warning: Dereference of null pointer (loaded from variable 'i')
  return *i;
         ^~
1 warning generated.
scan-build: Removing directory ... because it contains no reports.

Thus even though the error is detected correctly no report is generated for it.
