[Cppunit-devel] unexpected SIGSEGV on CPPUNIT_FAIL

[Thomas D. <th...@dr...>]

Hello,

can anybody help me, to find the reason why CPPUNIT_FAIL 
cause a SIGSEGV.
thx in advance.

----------------------------------------------------------------------------------------
ostringstream ostr;
....

	} catch (const Exception &e ) {
//		if( e.Errno() != EINVAL ) {
			ostr.str("");
			ostr << mesg.shortDescription()
			     << "\n-- Unexpected Dns::Exception received !! \n--" 
			     << e.message() << "--\n";
			cout << endl << ostr.str() << endl << endl; // here's nice output
			CPPUNIT_FAIL( ostr.str() ); // got sigsegv
//		}
	}
---------------------------------------------------------------------------------------

From experience such failure are caused by wrong or inconsistent compilation 
option. The CPPUNIT_FAIL throw an exception. I'd would recommend inlining 
the macro code and stepping into CPPUNIT_FAIL code with a debugger to see 
what is happening.
