I have seen this since SCons 2.0

Are you saying 2.3.0 was fine but 2.3.1 rebuilds needlessly? Or is this something that was there in 2.3.0?

I have the same issue with the build at my job. I thought it might have been bug in Parts passing data around, a badly define build files that dependson stuff differently if something exists on disk or not ( ie something that is built). However I pretty sure there is a bug in SCons. I leaning towards bugs in way signatures are made.. honestly this is where I go bad to needing to refactor scons. The plus side it seems to happen for me only on one or two cases out of 90k different outputs for the build. Parts tends to get around this when it skips loading the Parts file that defines these nodes as for some reason the corruption seems to happen when the build file happens, the existing stored state seems to be correct.

I'm also getting some spurious rebuilds with 2.3.1 compared with 2.3.0.  Will dig into it.  Dirk, I'm not sure if it's your patch or something else that changed....

I created a pull request, switching off the memory savings for the Interactive mode completely. Just to be extra careful...

With this, we should get rid of the observed problems.

I'm not using interactive mode.  This is just regular repeated builds.
Oh, I see. Do you have something like a series of steps for reproducing the error(s)?

No, sorry; it happens on my day-job project which is huge and proprietary.  I did spend some time on it today but scons just says it's rebuilding for an unknown reason.  I suspect (?) it might have something to do with a dir as a source.
