Exception in SDO runtime on Windows using VC++ Express 2005
-----------------------------------------------------------
Key: TUSCANY-719
URL: http://issues.apache.org/jira/browse/TUSCANY-719
Project: Tuscany
Issue Type: Bug
Components: C++ SDO
Affects Versions: Cpp-current
Environment: Windows and VC++ Express 2005
Reporter: Geoff Winn
Priority: Minor
Here's the Exception and call stack I'm getting from sdo_test on
Windows, built with VC++ Express 2005:
msvcp80d.dll!104f9961()

The exception is raised in list.cpp - line 309:
#if _HAS_ITERATOR_DEBUGGING
void _Compat(const _Myt_iter& _Right) const
{ // test for compatible iterator pair
if (this->_Mycont == 0 || this->_Mycont != _Right._Mycont)
{
_DEBUG_ERROR("list iterators incompatible"); <---- There
_SCL_SECURE_TRAITS_INVALID_ARGUMENT;
}
}
This is called from DataObjectImpl::~DataObjectImpl():
PropertyValueMap::iterator i = PropertyValues.begin();
while (i != PropertyValues.end())
{
unset((*i).first);
if (i == PropertyValues.begin()) <-- There
{
// unset has not removed the item from the list - do it
// here instead
PropertyValues.erase(i);
}
i = PropertyValues.begin();
}
And I am a little puzzled by the code in the above loop... Although I
didn't spend much time trying to grasp the logic here, and I have not
been playing with C++ iterators too much lately, my experience is that
removing entries from a collection that you're iterating on is usually a
sure way to shoot yourself in the foot :) so I may be wrong but I sense
a bug somewhere in this loop...
