There is another problem with :outer. It does not let you create inner
functions dynamically. For example, I couldn't use it to compile next
ECMAScript code:
function outer() {
var i = 0;
return eval(function() { return i++; });
}
Is it not possible to have an opcode that
One temporary workaround that I considered for this problem
would be to have eval() use introspection on its caller to
create a wrapper sub that duplicates the lexical environment of
the caller, and then use that as the target of an :outer()
flag when it's passed to imcc. For example, the

There is a memory leak with the STRING's. Next C code consumes more
I think that the leak is at CParrot_PCCINVOKE.
I tested it that way:
test.pmc
#include parrot/parrot.h
pmclass Test
dynpmc
group pjs_group
hll Pjs {
void set_integer_native(INTVAL ignore) {
int i;
for(i=0;i1000;i++) {
We could maybe assume that the ordering is well defined between the
instances of a PMC class. But cmp needs to compare instances of
different PMC classes as well, for which a well defined ordering is
less probable.
I would not be surprised if in some dynamic language all of a==b, ab
and ab

[Sorry chromatic, forgot to send to the list]
Did you happen to catch which PMC it is that's leaking?
I don't know which PMC, but the leak happens when you create a
PMCProxy with init_pmc.
Also, is this with PIR or PBC or both?
Both.
Do you have a short test case that Valgrind catches?

I agree. See

-Parrot_free_context(INTERP, from_ctx, 1);
I don't know much about this context stuff, so maybe I don't see
something, but how are those contexts freed after your patch?
Hello,
PJS (Parrot JavaScript) allows a number to be NaN. The result of
comparing an NaN to any value is false (thus all of NaN == NaN, NaN
NaN, NaN NaN, NaN = NaN, NaN = NaN evaluate to false).
There is only the vtable function Ccmp that a PMC can implement to
define ordering.
Parrot assumes
I don't think that the code is safe, but it does what it means :)

What about a real_exception variant that accepts STRING*'s as arguments?
On the other hand, as you said, there will be other functions which
don't return control (functions that call real_exception etc.). But
then char* is not the only problem, any malloced data can leak.

It seems to work in general, but in some cases (especially when I

It was caused by some unitialized memory in src/mmd.c. rt #43105 solves it.

The results of my first post in this thread were probably caused by

you might have run into a Garbage-Collector bug. Try
