[Cppunit-devel] Core dump using CPPUNIT_ASSERT_EQUAL on strings

[Dave D. <da...@dr...>]

Hello,

I've come across a core dump while using CPPUNIT_ASSERT_EQUAL on
strings.  I've attached a tarball with a few source files and a README
explaining how to reproduce it.  I've attached the README, too.

Note: I am not subscribed to the list, so please CC me on any replies.

From the stack trace, it seems that
TestAssert.h:46
      static std::string toString( const T& x )
      {
          OStringStream ost;
          ost << x;
          return ost.str();        //  <<  throw an exception...
      }

Could you:
- dump the exception
- tell me what are the value of
CPPUNIT_HAVE_SSTREAM
CPPUNIT_HAVE_CLASS_STRSTREAM
CPPUNIT_HAVE_STRSTREAM
in the generated config file cppunit/config-auto.h.

The problem is likely an OStringStream issue that depend on your
configuration.

Baptiste.

Sorry for my ignorance, but how do you do that? :)  I tried doing
this:

void Suite2::test_case1()
{
    try
    {
        string a = "2a";
        string b = "2b";

        CHECK_EQUALS(a, b);
    }
    catch(std::exception & e)
    {
        cerr << "Caught exception: " << e.what() << endl;
    }
}

But a SIGABRT still happens in CHECK_EQUALS() and the catch block
never runs.

#define CPPUNIT_HAVE_SSTREAM  1 
#define CPPUNIT_HAVE_CLASS_STRSTREAM  1 
#define CPPUNIT_HAVE_STRSTREAM  1

If I remember ostringstream's weren't in GCC 2.95.  But Red Hat's 2.96
is a bastard child somewhere between 2.95 and 3.0.x.
