However, there is a long-standing issue with stdout/stderr logging: if the process dies before systemd has had a change to process its log message, then systemd may not be able to figure out the unit corresponding to the message, so it may be lost (or not attributed to the unit). Seehttp://lists.freedesktop.org/archives/systemd-devel/2012-June/005590.html
I didn't investigate details, but I suspect that losing the last parts of logs could be caused by the fact that stdout is buffered by default (and stderr is not). I don't know if the contents of the buffer residing in the crashed process can be well recovered. Perhaps they have some hack to force the flush externally, I don't know.
See e.g. http://stackoverflow.com/questions/7876660/how-to-turn-off-buffering-of-stdout-in-c
