I'm baffled that it works for anyone else... perhaps some bizarre quirk of shell syntax causes the output of one line to automagically become the input of the next, if conditions are correct?  The mechanism by which it is somehow accidentally working for other people is beyond my knowledge of shell scripting.

    97	dd count=20 bs=100K if=/dev/zero status=none |
    98	{
    99	  dd count=0 oflag=nonblock status=none
   100	  tee || { cleanup_; touch tee.fail; }
   101	} >fifo

Both commands between the { ... }, i.e., dd(1) on line 99 and tee(1),
are consuming the input from the dd(1) command on line 97.

Several of the tests do deem themselves inapplicable for reasons that don't appear to match reality, such as tests/csplit/csplit-heap.sh believing that `ulimit -v` is absent when it is present; but as those are not actual test _failures_, I am disinclined to spend time digging into them unless someone specifically asks me to.

Thanks for the reports, but please also provide the original testsuite.log as
'make check' instructs at the end of the output.  We need it to analyze further.

Have a nice day,
