Hi Eric!
Thanks for the bug report! Tracking that as an issue on github [1] now.
You don't happen to have a fix that you've tested already?
Best regards,
Marcus

I am using the Stream CRC32 block and was having trouble getting the
CRCs to pass. After some debugging I discovered that the
calculated CRC is different depending on whether or not the source
data is packed. This can be observed using the attached flow graph.
The result of the packed stream appears to be correct. I looked at the
code for the block (crc32_impl_bb.cc) and that see that regardless of
the Packed setting in the block the CRC calculated with:
d_crc_impl.process_bytes(in, packet_length);
I believe that for the unpacked case, either the bits need be repacked
before the calculation or repeated calls to process_bits should be
used in place of the the call to process_bytes.
My version of gnuradio is: 3.7.12git-126-g37d373ac
Thanks!
Eric
