index out of range panic #142
Description
Unable to reproduce through unit test for the time being, but it does exist in my application. I write a batch of documents to bluge through Batch, then query them and delete them. Then write new documents, keep looping. My program seems to crash randomly.
panic: runtime error: index out of range [559] with length 4

After reading the code, I found that this is related to cleaning up the old document when merging the segments, but I passed the unit test and failed to reproduce it. I really don't understand why it is accessed out of bounds, which may be related to the maintenance of bitmap?
