Comment (by pdziepak):
To be exact, this bug (either in Haiku or in this particular application)
might have been there earlier but ASLR made it result in a page fault.
Before hrev45518 there was no gaps between areas (unless one of them was
deleted) thus an incorrect address before the start of the buffer was
still valid from the kernel point of view (since there was another area
before the one we wanted to access). Now, there are random gaps between
areas and such incorrect addresses almost always result in a page fault.
