Consider the following script:
#!/usr/bin/ksh93t
print "KSH Version: ${.sh.version}"
typeset -T Pt_t=(
float -h 'length in inches' x=1
float -h 'width in inches' y=0
# if next line is uncommented causes core dump when r1 is instantiated
# integer -S count=0
len()
{
print -r $((sqrt(_.x*_.x + _.y*_.y)))
}
)
typeset -T Rect_t=(
Pt_t ll=(x=0 y=0)
Pt_t ur=(x=2 y=2)
area()
{
print -r $((abs((_.ur.x-_.ll.x)*(_.ur.y-_.ll.y))))
}
)
# create an instance of r1
Rect_t r1
print "R1 AREA: ${r1.area}"
exit
I get a core dump if I uncomment the "integer -S count=0" line.

Is the use of a shared variable, i.e. count, unsupported in this type
of definition?
