Error when calling dump_all

[edraut]

I've been using memprof with my project, specifically the stats and dump methods. They work perfectly. However, when I attempt to use the dump_all method, I get this:

<Memprof::Unsupported: not enough config data to dump heap>

Can you tell me if this is a bug or if there is some configuration I need to do?

I'm running REE 1.8.7 2011.03

Thanks,
Eric

It doesn't look like the error you posted actually appeared in this post.

I'm also seeing an error when I call "dump_all":

1.8.7 :001 > require 'memprof'
Failed to determine offset of heaps_slot->limit

You won't be able to dump your heap!

I'm using the latest version of REE, 2012.02, CentOS 6.2, 64 bit

Any idea on what I need to configure?
