In other places, you don't use blr_buffer. There's a GDML command that
translated by GPRE into BLR. But here, due to the goal that needs to be
achieved, the binary commands are assembled directly by gbak.

Nothing special. The code in that function found that it needed an alignment
for some field and this raised the length from 46 to 48.

Not for now. We need to know why the engine itself is apparently stuck.
