Comment(by plobsing):
Replying to [ticket:132 coke]:
It appears that not even a Sub proper can be thawed (likely because Subs
aren't first class citizens as far as PBC is concerned).
Code:
{{{
.sub main :main
.local pmc pirC
pirC = compreg 'PIR'
.local string code
code = <<"END_CODE"
.sub bar
say "hi"
.end
END_CODE
.local pmc compiled
compiled = pirC(code)
.local pmc sub
sub = compiled[0] # just want the first executable sub here.
sub() # works
$S0 = freeze sub
say "frozen"
$P2 = thaw $S0
say "thawed"
$P2()
.end
}}}
Output:
{{{
hi
frozen
thawed
zsh: segmentation fault ./parrot test2.pir
}}}
