I see what you mean; changing the code to this:
new P0, .PerlInt
new P1, .PerlInt
new P3, .PerlInt
set S0, "Brown"
set P0, "Yes"
setprop P1, S0, P0
set S0, "Black"
set P3, "No"
setprop P1, S0, P3
new P2, .PerlString
getprop P2, "Brown", P1
print P2
print "\n"
getprop P2, "Black", P1
print P2
print "\n"
end
does indeed print:
Yes
No
This still doesn't answer my question, though: is the fact that the keys
are passed by reference a bug or a feature?
Also, the above code (and the original version) still segfaults if I run
it with --gc-debug.
