Copying .sh.sig data in a namespace doesn't work either:
namespace a.b
{
compound c
compound -a c.car
integer c.cari=0
trap 'c.car[$((c.cari++))]=.sh.sig' USR1 USR2 RTMIN
kill -q4 -s USR1 $$
kill -q17 -s USR2 $$
print -v c
}
This prints:
ksh x.sh
x.sh: line 9: .sh.sig.value.ptr: is read only
x.sh: line 10: .sh.sig.value.ptr: is read only
(
typeset -C -a car=(
[0]=(
typeset -C value
)
[1]=(
typeset -C value
)
)
typeset -l -i cari=2
)
This is dead wrong. It should print the copied siginfo (.sh.sig) data.
