Fix compression segfault
...
When the overflow protection kicks in, it makes sure that ip - ctx->base
isn't too large. However, it didn't ensure that saved offsets are
still valid. This change ensures that any valid offsets (<= windowLog)
are still representable after the update.
The bug would shop up on line 1056, when `offset_1 > current + 1`, which
causes an underflow. This in turn, would cause a segfault on line 1063.
The input must necessarily be longer than 1 GB for this issue to occur.
Even then, it only occurs if one of the last 3 matches is larger than
the chain size and block size.
