Silent error when running extractHAIRS #7
Description
I am encountering a silent error in extractHAIRS. I run extractHAIRS and see that it stops output fragments part way through the input file. The exit code returned by extractHAIRS is 0!
I ran it through gdb and found the following:

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
I updated both the samtools and htslib submodules to master and re-ran extractHAIRS and got:
reading sorted bamfile ../../path/to/BAM
[E::bgzf_read] bgzf_read_block error -1 after 27499 of 107505 bytes
The reads in the SAM file are very long so my suspicion would be with the underlying htslib/samtools code, but I would be happy to share my test case privately.
