* [tests/memory.c] Call "fflush (NULL)" before abort() in order to flushvlefevre2021-01-141-0/+10
| | | | | | | | | | | all the output streams, in particular the log file (when there is one), so that setting MPFR_LOG_FLUSH (which may be inefficient) is not needed to debug tests that end with a memory error. This fixes a regression with glibc 2.27+: the streams are no longer flushed by abort(), as permitted by POSIX; see the abort(3) man page. git-svn-id: https://scm.gforge.inria.fr/anonscm/svn/mpfr/trunk@14258 280ebfd0-de03-0410-8827-d642c229c3f4
