Re: [COMMIT] GC_DEBUG, Some GC Fixes, and Remaining GC Bugs

This is a patch that clears up all of the GC_DEBUG-revealed bugs, at least on my machine. As I enumerated in my previous email, there are a lot of different ways to fix these sorts of problems, and this just kinda picks one for each problem encountered. This patch includes the stuff done by Jason

Re: [COMMIT] GC_DEBUG, Some GC Fixes, and Remaining GC Bugs

In tracing down the next crash bug using GC_DEBUG, I found that the following code in new_stack is unsafe: stack->buffer = new_buffer_header(interpreter); Parrot_allocate(interpreter, stack->buffer, sizeof(Stack_Entry_t) * STACK_CHUNK_DEPTH); A GC can be triggered by

[PATCH] new op in core.ops

Well, I don't know if this is interesting, but here's a patch that implement: op rand(out NUM) op rand(out NUM, in INT) and does what you can guess. There's also a test file (I don't know wether the tests should go in an existant test file). But, there is a tiny, little problem: I don't c

[PATCH] core.ops and pod

One should begin with slight updates.. :) So this patch is just about pod in core.ops (unbalanced =over / =back, and a missing blank line). Btw, how do you prefer me to send patch (as if I were able to send more patches... anyway...): plain text inside the mail or attached (such as this one)?
