The following variation of Cedric's testcase doesn't crash but doesn't
print the correct .sh.sig data either:
-- snip --
$ cat test1.sh
compound c
compound -a c.car
integer c.cari=0
integer trap_i
trap '(( trap_i=c.cari++ )) ; typeset -c "c.car[$trap_i]=.sh.sig"' USR1
kill -q4 -s USR1 $$
kill -q5 -s USR1 $$
true
print -v c
$ ./arch/linux.i386-64/bin/ksh -x test1.sh
+ typeset -C c
+ typeset -C -a c.car
+ c.cari=0
+ typeset -li c.cari
+ typeset -li trap_i
+ trap '(( trap_i=c.cari++ )) ; typeset -c "c.car[$trap_i]=.sh.sig"' USR1
+ kill -q4 -s USR1 55344
+ (( trap_i=c.cari++ ))
+ typeset -c 'c.car[0]=.sh.sig'
+ kill -q5 -s USR1 55344
+ (( trap_i=c.cari++ ))
+ typeset -c 'c.car[1]=.sh.sig'
+ true
+ print -v c
(
typeset -C -a car=(
(
)
(
)
)
typeset -l -i cari=2
)
-- snip --
Grumpf... ;-(
