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++; }");
}

Thanks. That suppressed the leak in my first test cases. But I thin
I think that the leak is at C.
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;i<1000;i++) {
Parrot_PCCINVOKE(INTERP, SELF,
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 evaluate to fa
I agree. See

I don't know which PMC, but the leak happens when you create a
PMCProxy with init_pmc.

Both.

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 C 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 :)

It seems to work in general, but in some cases (especially when I
allocate too much memory) it causes me a segfault
or an error like: Trace/breakpoint trap (core dumped)
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
the fact that some files were not updated correctly (I am new to
revision control). Both Allison's and Alek's patches have in fact the
same effect.

Shouldn't that be 'format[sizeof(format) - 1]' ?

## file tail.pir
I have rewritten the grammar. There are some problems though.
- I don't know how to express thinks like: an identifier is
<[a..zA..Z_$]>*, but not a . Something like: rule identifier
{<[a..zA..Z_$]>*} seems not to allow identifiers that have
keywords as prefix.
- I couldn't make comments work.

Hi Mehmet,
you might have run into a Garbage-Collector bug. Try
parrot --no-gc main.pir 'x' 'identifier'
I had similar problems using PGE::P6Regex. '--no-gc' helped.
Regards,
Kiwi
The same problem.
I think that I now know the problem: the grammar is not complete. I
was thinking that pgc
js.pg in languages/ecmascript/src compiles just fine with pgc. But it
gives a "Null PMC access" error while using the compiled pir file. Is
it a pge bug?
$ cd languages/ecmascript/src
$ cat main.pir
.include 'errors.pasm'
.sub _main :main
.param pmc args
.local string source_code, rule_t
I am too planning to implement ECMAScript. I do not yet know how, I
have to experiment with parrot first.
