[Scons-users] Errors in parallel builds after updating from SCons 2.3.0 -> 2.3.5

[mg at ncp-e.com]

Hello,

recently I've updated from SCons version 2.3.0 to version 2.3.5 and
since then I'm getting this type of errors when doing parallel builds
with a large number of jobs like '-j 8':

------------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/lib64/python2.7/site-packages/SCons/Action.py", line 1063, in execute
    result = self.execfunction(target=target, source=rsources, env=env)

    env['tpi'].install(env, env['tpi_instdir'])

    inst_node = env.Install(instdir, lib.str())[0]

    if t.get_executor().get_all_targets() != tlist:
AttributeError: 'NoneType' object has no attribute 'get_all_targets'
------------------------------------------------------------------------

I was looking into this but couldn't find any obvious error in my parts
of the code. And it worked fine before the update. So might this be a
new issue within SCons?

The error seems almost always reproducible and is always in the same
spot depending on which target I'm trying to build. The build is running
on Linux if this is of any relevance.

I'm glad for any help.

Best Regards

Matthias
