    Description

      I have a separate disk where I store all git and bzr trees: /media/DATA/maria-bzr/.

      There is a convenience symlink from home directory:

      cd ~
      		 
      ln -s /media/DATA/maria-bzr/  .

      Now I clone a tree:

      cd maria-bzr
      		 
      bzr clone bzr+ssh://bazaar.launchpad.net/~maria-captains/maria/10.0/

      And compile an out-of-source build:

      cd 10.0
      		 
      mkdir bld
      		 
      cd bld
      		 
      cmake .. -DCMAKE_BUILD_TYPE=Debug
      		 
      make -j8

      Now I run a test:

      cd mysql-test
      		 
      ./mtr --mem ctype_utf8

      It ignores the --mem option and creates a real var subdirectory under the current directory, instead of symlinking it to a random sub directory at /dev/shm/.
      As a result, the entire ./mtr runs about 4 hours instead of 20 minutes.

      Note, it works as expected when I use a in-source tree:

      cd ~/maria-bzr/10.0/
      		 
      rm -rf bld
      		 
      cmake . -DCMAKE_BUILD_TYPE=Debug
      		 
      make -j8
      		 
      cd mysql-test
      		 
      ./mtr  --mem ctype_utf8
