This is interesting.

On a side note: At the time of compilation your tinderbox had only about 32GB of memory free but you issued -j16 parallel jobs. Some of the compilation units of deal.II require more than 2GiB of main memory at the moment. So if you got unlucky the build process might have triggered the OOM killer. On the other hand, there seems to be no killed process due to OOM.(?)
