Assembly language and register values included as an attachment. Each section is
separated by '========'. There are are five section; {1} operator new() source
code, given below, {2} disassembly of code when a virtual base class destructor
is used; (3) register values immediately before the failure; (4) disassembly of
code when a virtual base class destructor is not used; (5) register values
before the final call.
I have a direct call to a concrete destructor (delete header) in a derived
class. The code generated when the base class constructor is virtual is
different then when the base class destructor is not virtual. The code generated
fails when the base class destructor is virtual and works correctly when the
base class destructor is not virtual.
Without going into too much detail, I am reimplementing Weizenbaum's SLIP in
C++. I use my own memory allocator. When memory is deleted it is put at the end
of a list of available space. Allocation is from the front of the available
space list. A sublist contains a pointer to the header of a list. During
allocation when the allocated space refers to a sublist then the associated
header contained in the sublist is deleted. The failure occurs in the inline
code associated with 'delete header'. Assembly language 'call' statement used
register eax which contains a zero, generating a fault on the call.
It is quite possible that I haven't implemented or understood the care and
feeding of virtual destructors. But a single line change causing this type of
damage is baffling, and all the non-sublist deletes seem to work correctly.
Sigh.
If I haven't said things correctly or if the things said are muddled and lack
reason, please correct me, don't punish me.
The base class destructor is ~SlipCell() { } in the base class header file.
The allocation code in the file SlipCell.cpp is; "operator new(size_t size);
void * SlipCellBase::operator new(size_t size) { // Create a new SLIP
cell
SlipCellBase* link;
do {
if (avsl.top == NULL) {
SlipCellBase::getAVSLSpace();
}
link = (SlipCellBase*)avsl.top;
avsl.top = avsl.top->rightLink;
avsl.avail--;
} while((long)link == TEMPORARY );
SlipOp* op = *(SlipOp**)link->getOperator();
if (op->isSublist()) {
SlipHeader* header = *(SlipHeader**)getSublistHeader(*link);
cout << link->dump() << endl
<< header->dump() << endl << flush;
delete header; // <== point of failure
}
/* Zero Cell */
link->setOperator((void*)undefinedOP);
link->rightLink = link->leftLink = (SlipCellBase*)UNDEFDATA;
link->resetData();
return link;
}; // void * SlipCellBase::operator new(size_t size)
The inline delete method in the file SlipHeader.h is:
~SlipHeader() { deleteHeader(); }; // ~SlipHeader()
void deleteHeader() {
if (*(getHeadRefCnt()) <= 1) {
addAVSLCells( this // pointer to first cell
, getLeftLink()); // pointer to last cell
} else
*(getHeadRefCnt()) -= 1;
}; // void deleteHeader()virtual ~SlipCell() { } // virtual base class destructor
SlipCellBase::operator new(size_t size);
Source Code in SlipCell.cpp
void * SlipCellBase::operator new(size_t size) { // Create a new SLIP cell
SlipCellBase* link;
do {
if (avsl.top == NULL) {
SlipCellBase::getAVSLSpace();
}
link = (SlipCellBase*)avsl.top;
avsl.top = avsl.top->rightLink;
avsl.avail--;
} while((long)link == TEMPORARY );
SlipOp* op = *(SlipOp**)link->getOperator();
if (op->isSublist()) {
SlipHeader* header = *(SlipHeader**)getSublistHeader(*link);
cout << link->dump() << endl
<< header->dump() << endl << flush;
delete header; // <== point of failure. Code generated
// is different for virtual vs.
// non-virtual base class destructor
