[Scons-users] Problem with Repository build

[Martin Ritter]

Hi all,

we have a problem building our software with SCons versions newer than 
2.2.0 [1] when using env.Repository()

Compilation without the Repository() setup works fine.

I think it is caused by the fact that Node.FS.File.release_target_info() 
sets self.executor to None. If I remove that line it seems to compile 
fine. This error also does not seem to happen for all targets, just for 
a subset of them.

Best Regards,

Martin

[1] it works with 2.2.0, I checked 2.3.6 and 2.5.0, both show the same error
