Thanks Gary. http://scons.tigris.org/issues/show_bug.cgi?id=2982
I started to add some additional trace to Taskmaster.py, and compare the logs from sequential vs. parallel builds. The bug seems to relate to how the node states are used for the side-effect nodes: - In executed_with_callbacks(), the side-effect state is set to NODE_NO_STATE. - In postprocess(), the logic to decrement the parent ref count is only active for a side-effect node with state NODE_EXECUTING. Although this helped me to understand the bug a bit better, I'm not sure what is the correct fix.

Please file a ticket! The dependency tree looks OK, and I can't easily see the cause of the bug. Adding sf0 and sf1 to the targets list instead of as side effects makes it work. -- Gary _______________________________________________ Scons-dev mailing list Scons-dev@scons.org https://pairlist2.pair.net/mailman/listinfo/scons-dev _______________________________________________ Scons-dev mailing list Scons-dev@scons.org https://pairlist2.pair.net/mailman/listinfo/scons-dev
