Subject: Fix the memory usage of the /source/fe unity files.
X-Git-Tag: v9.0.0-rc1~407^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=18b668de1a7c6d44e453e894c2bb8672dd2df2c9;p=dealii.git

Fix the memory usage of the /source/fe unity files.

Recent changes, such as b15febd0c2, 36b74d6ee1, and fd1bf6a6f8 caused the memory
usage of one of the unity files to go above 5 GB: these splits lower the high
water mark to about 3 GB.
