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
|
||

||

|
