So I experimented further on until I realized that it is an
optimization issue:
$ g++ -Wall -O2 unarbc0.cpp bit_byts.cpp -o unarbc0
$ g++ -Wall -O2 arbc0.cpp bit_byts.cpp -o arbc0
produces the bad versions which don't work properly, whereas
$ g++ -Wall arbc0.cpp bit_byts.cpp -o arbc0
$ g++ -Wall unarbc0.cpp bit_byts.cpp -o unarbc0
gives correctly working tools.
Then there is almost certainly a bug in the code, which the
unoptimized version is accidentally suppressing. Time to break out the
debugger.
