\section1 Maximum size and out-of-memory conditions
The current version of QByteArray is limited to just under 2 GB (2^31
bytes) in size. The exact value is architecture-dependent, since it depends
on the overhead required for managing the data block, but is no more than
32 bytes. Raw data blocks are also limited by the use of \c int type in the
current version to 2 GB minus 1 byte.
In case memory allocation fails, QByteArray will throw a \c std::bad_alloc
exception. Out of memory conditions in the Qt containers are the only case
where Qt will throw exceptions.
