It looks like a setjmp/setsigjmp -> longjmp/siglongjmp goes
wrong here. This because it is not a real SIGSEGV but only
the message about. The script sniplet which fails is a three
liner:
myfilter() { x=$(print ok | cat); print -r -- $SECONDS;}
set -o pipefail
sleep 3 | myfilter
please note that if I add a line like
type cat
before the first line it works. To reproduce this I've
to deinstall ksh and run the test within the build
tree like:
base=src/cmd/ksh93
root=$(echo ${PWD}/arch/linux*)
test=${PWD}/${base}/tests
pushd ${test}
LD_LIBRARY_PATH=${root}/lib ${root}/bin/ksh /tmp/scriptlet
which is simply what is done within the build environment.
Please note that I using shared libraries for libast, libcmd,
libdll, and libshell. Therefore the LD_LIBRARY_PATH variable
is set.
