[Nix-dev] nix killed by 11

[Marc Weber]

Hi,

I tried rewriting the jobs in nixos using an attrset so that settings
can be overwritten easily.

Eg 
services.sshd.enable = true
services.sshd.startOn = "never"

The purpose is to add sshd to nixos-install so that you can start it by
start sshd

However when instantiating the system derivation nix is killed
(segfault).

I talked to niksnut briefly. He said that this is probably the fault of
nix.
Which is the best way tracking down the cause?

valgrind looks like this:
These Conditional jump or move depending on uninitialised values should
be fixed, should they?

Is this a way to start finding this bug?
I've uploaded the full valgrind log here:
http://mawercer.de/~marc/all.log.gz

So does this look like a bug in aterm? If so how to proceed? Is there an
upstream version I should try first?
