possible crash when calling qUncompress() with different data (under Windows)

Calling qUncompress() with corrupted data must return empty QByteArray, but ...

example

...
    QByteArray ba("var Q");
    ba = qUncompress(ba);
...

crash with message

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

many variants of data, it is the shortest that I found.
under linux(Ubuntu 9.10) this is no problem.
