Try bash-4.4. I think this was fixed back in the middle of August. The bash-4.3 implementation of save_ and restore_pipeline only provided one save level, and multiple calls would try to access freed memory. Depending on your malloc implementation, this had different effects, all bad. http://lists.gnu.org/archive/html/bug-bash/2015-08/msg00060.html is the original bug report for this. -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, ITS, CWRU c...@case.edu http://cnswww.cns.cwru.edu/~chet/
