An update: this bug is *not* related to debian, but requires certain compiler
settings. I now also get it on Fedora. Also, it has nothing to do with the
named pipe. In fact, there seems to be a problem with the way direct queues
are handled. I don't have full details yet, but finally I begin to understand
the issue. It is a v5-only bug, introduced by the new queue engine. Direct
queues (at least action queues) can cause a segfault, at least if something
goes wrong in the action. Will post more details and/or a fix when I have
better info.
