[Valgrind-users] Warning: set address range perms: large range 134217728

[Joshua Moore-Oliva]

I get this output, and a message to submit this data.. I have no idea what it means, but here it is..

How do I work around this?

Thanks, Josh.

I was allocating a stupidly large buffer, that is the cause of the error...

although, as a suggestion it could be a little more specific in the error.

It means you ran out of memory. valgrind 2.1.1 appears to be quite a
memory pig compared to previous versions.

Installing more RAM in your computer might help. I recall reading on the
-developer list that there's a patch to decrease some of valgrind's
demand for RAM. Hopefully it will be publically released soon.

I don't think installing more RAM would help. The issue isn't physical
memory, rather address space. 2.1.1 does do not so well here; the
current CVS version has some improvements in this respect, and I'm looking
at improving things further. The CVS version also no longer asserts when
malloc() fails, rather it just returns NULL as standard.

If you really need to do big mallocs like this and Memcheck is failing,
you could try Addrcheck as it uses less memory.
