Description:
On 64 bit system having not more than 4GB main memory the test program "query_prealloc_size_basic_64.test" corrupts the operating system, as the test tries to allocate more than 4GB of main memory. That leads to very long run times of that test or to system exceptions.

How to repeat:
Don't try.

Suggested fix:
Take out the values > 4GB. Use also smaller values on 64 bit platforms. Larger values may be used in a separate test running on selected 64 bit machines only, which have more than 4GB RAM.
