[Libreoffice] build failure in tail_build

Recently my build fails in tail_build.

When I do 'make' after 'make clean', I got the following (last several
lines):

Following the instructions above (with clean), it finishes successfully (no
error message at the tail, and exit code is 0).
But If I then go back to root and do 'make' again, the result is the same.

autogen.sh options are:


> ./autogen.sh --enable-symbols --disable-strip-solver --enable-werror
> --enable-debug --enable-dbgutil --enable-crashdump --enable-verbose
> --with-max-jobs=2 --with-num-cpus=2

current commit is: 7d7496bd4c152ad1746809800f1298169052320e

Do you have any ideas to fix this?
