There are several places in imageFile.cpp where "delete" operator is used instead of "delete []" for objects allocated with "new []":

...
_data = new u1[(size_t)data_size];
...
// Release module data resource.
ImageModuleData::~ImageModuleData() {
    if (_data) {
        delete _data;
    }
}
...

...
ImageFileReaderTable::ImageFileReaderTable() : _count(0), _max(_growth) {
    _table = new ImageFileReader*[_max];
}

ImageFileReaderTable::~ImageFileReaderTable() {
    delete _table;
}
...

...
_name = new char[len];
...
ImageFileReader::~ImageFileReader() {
    // Ensure file is closed.
    close();
    // Free up name.
    if (_name) {
        delete _name;
        _name = NULL;
    }
}
...

...
compressed_data = new u1[(u4)compressed_size];
...
delete compressed_data;
...

As far as I know, behavior is undefined in this case. It would be better to use delete[]:
