This does not add missing release notes, and it doesn't do anything
about the profiles feature we would really like to have so we can have
consistent credit.

|
The number of nested function calls has been restricted, to detect and report
|
|
infinite function call recursions. The default maximum call depth is 10,000 and
|
|
can be set with [the `max-call-depth`
|
|
option](@docroot@/command-ref/conf-file.md#conf-max-call-depth).
|
|
|
|
This fixes segfaults or the following unhelpful error message in many cases:
|
|
|
|
error: stack overflow (possible infinite recursion)
|
|
|
|
Before:
|
|
|
|
```
|
|
$ nix-instantiate --eval --expr '(x: x x) (x: x x)'
|
|
Segmentation fault: 11
|
|
```
|
|
|
|
After:
|
|
|
|
```
|
|
$ nix-instantiate --eval --expr '(x: x x) (x: x x)'
|
|
error: stack overflow
|
|
|
|
at «string»:1:14:
|
|
1| (x: x x) (x: x x)
