每当执行throw语句时,我都会遇到分段错误.这是Valgrind输出的原因.我不知道发生了什么事.

我已经进行了多次单元测试的重复轰炸,但是现在这是与其他所有相同的错误:
- void CollectionFactoryTest::testCreateNewFromMap_InvalidName()
- {
- const char* MAP_FILE =
- "smallMapWithThreeSets.xml";
- const char* NAME1 = "name/invalidname";
- const char* NAME2 = "name/invalidname";
- DataMapReader dmr;
- DataMap dm = dmr.getDataMapFromFile(MAP_FILE);
- CollectionFactory cf;
- try
- {
- cf.createFromMap(NAME1,dm);
- }
- catch (std::exception const& e)
- {
- std::cerr << e.what() << std::endl;
- }
- /*CPPUNIT_ASSERT_THROW(cf.createFromMap(NAME1,dm),std::invalid_argument);
- CPPUNIT_ASSERT_THROW(cf.createFromMap(NAME2,std::invalid_argument);*/
- }
每个请求,isNameValid的内容:
- bool Collection::isNameValid(const std::string& name)
- {
- /* can't be blank */
- if(name.length() == 0)
- {
- return false;
- }
- /* Can't contain '/' */
- if(name.find('/') != std::string::npos)
- {
- return false;
- }
- return true;
- }
