| Subject: | Segmentation faults possible |
t/06_compat.t sometimes fails, obviously because of a segmentation fault. See
http://matrix.cpantesters.org/?dist=Text-ClearSilver%200.10.5.4
for an overview of fail/pass reports.
valgrind also shows a problem:
$ valgrind perl5.22.1-RC1 -Mblib t/06_compat.t
