build error with "impossible constraints"

[holiman]

For some reason, this happened when I tried building a docker image on one machine -- but not when I build it on another. Any idea what can be the cause of this?

The failure come from a C library linked with Nim(libsecp256k1). I suspect it is because of the C conditional compilation problem.

similar error message: waku-org/nwaku#2560. Are you using the new AMD CPU too? @holiman

[namiloh]

Not sure. @fredriksvantes do you know? It was on the boulder02 machine
