Seen trying to rebuild the world on core-updates, with gawk-5.1.0:
--8<---------------cut here---------------start------------->8---
for i in _* ; \
do \
if [ "$i" != "_*" ]; then \
echo ============== $i ============= ; \
base=`echo $i | sed 's/^_//'` ; \
if [ -r ${base}.ok ]; then \
diff -c ${base}.ok $i ; \
else \
diff -c "."/${base}.ok $i ; \
fi ; \
fi ; \
done
============== _sigpipe1 =============

system
pipe to command
! pipe from command
--- 1,4 ----
system
pipe to command
! gawk: sigpipe1.awk:7: fatal: print to "yes | true" failed: Broken pipe
! EXIT CODE: 2
Re-running later
--8<---------------cut here---------------end--------------->8---
On a second attempt the same test passed.
