Hmm I don=E2=80=99t think so. The bug here is likely due to 32-bit signed integer wrapping. That can only happen in C code, so to me possible culprits would be guile-simple-zmq or the layer above it (if there=E2=80=99s a binary protocol involved) or the postgresql interface. Only a vague intuition, though. Ludo=E2=80=99.
