pennae fd5aa6ee3e allocate a GC root value for the Value cache pointer 
keeping it as a simple data member means it won't be scanned by the GC, so
eventually the GC will collect a cache that is still referenced (resulting in
use-after-free of cache elements).

derivations.cc: Use larger buffer in printString 
If we want to be careful about hitting the stack protector page, we should use `-fstack-check` instead.

Eelco Dolstra 128098040b
Fix exception handling around realisePath() 
This no longer worked correctly because 'path' is uninitialised when
an exception occurs, leading to errors like

       … while importing ''

       at /nix/store/rrzz5b1pshvzh1437ac9nkl06br81lkv-source/flake.nix:352:13:

So move the adding of the error context into realisePath().

John Ericson 5ee937523d Add back copyClosure for plain StorePaths 
This was removed in 2e199673a5 when
`copyPath` transitioned to use `RealisedPath`. But then in
e9848beca7 we added it back just for
`realisedPath`.

I think it is a good utility function --- one can easily imagine it
becoming optimized in the future, and copying paths *violating* the
closure is a very niche feature.

So if we have `copyPaths` for both sorts of paths, I think we should
have `copyClosure` for both sorts too.

Robert Hensing dec7748119 Replace withBuffer by boost small_vector 
Although this will leave gaps in the stack, the performance impact
of those should be insignificant and we get a simpler solution
this way.

Robert Hensing d038a67bd3 Fix segfault or stack overflow caused by large derivation fields 
This removes a dynamic stack allocation, making the derivation
unparsing logic robust against overflows when large strings are
added to a derivation.
Overflow behavior depends on the platform and stack configuration.

For instance, x86_64-linux/glibc behaves as (somewhat) expected:

$ (ulimit -s 20000; nix-instantiate tests/lang/eval-okay-big-derivation-attr.nix)
error: stack overflow (possible infinite recursion)

$ (ulimit -s 40000; nix-instantiate tests/lang/eval-okay-big-derivation-attr.nix)
error: expression does not evaluate to a derivation (or a set or list of those)

However, on aarch64-darwin:

$ nix-instantiate big-attr.nix                                                                                                                                                                                                                                                       ~
zsh: segmentation fault  nix-instantiate big-attr.nix

This indicates a slight flaw in the single stack protection page
approach that is not encountered with normal stack frames.

regnat dd7c2e0695 Make nix why-depends quieter by default 
Unless `--precise` is passed, make `nix why-depends` only show the
dependencies between the store paths, without introspecting them to
find the actual references.

This also makes it ~3x faster
