QString failed to allocate the number of bytes requested. It stores 2 bytes for each character, because it internally uses UTF-16 coding units. With more than 1,000,000,000 characters it needs more than 2 GB. QString doesn't handle this, and porting away from QString would require a complete rewrite of the code.
