when offset == len(block_data) you are at the end of the data block, offset+4 cannot be referenced.
should either be:
while offset < len(block_data):
or
while ( offset + 4 ) <= len(block_data):

Appears to be a bug in RECFM_VB.

If offset == len(block_data), then the offset is larger than the available data. The block has been consumed; more data needs to be read.

In fixing the unit tests to reveal this problem, some bugs in the unit tests themselves were revealed.

Which, in turn, found another latent bug.
