Problems with Data Types, High Severity (5)
database.hxx
namespace odb
[+] class database (1)
| Change |
Effect |
| 1 | Pure virtual method database::execute ( char const*, std::size_t ) has been added to this class. | 1) Applications will not provide the implementation for this pure virtual method and therefore cause a crash in the library trying to call this method.
2) The layout of v-table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications. |

options.hxx
namespace details::cli
[+] class argv_file_scanner (1)
| Change |
Effect |
| 1 | Size of this class has been changed from 72 bytes to 92 bytes. | 1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications.
2) The memory layout and size of subclasses will be changed. |

query.hxx
namespace odb::mysql
[+] class query (1)
| Change |
Effect |
| 1 | Size of this class has been increased from 16 bytes to 28 bytes. | 1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighboring objects on the stack or heap.
2) The memory layout and size of subclasses will be changed. |

Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications.
2) The memory layout and size of subclasses will be changed. |
