Cannot extract standard library include paths - Linux

[Reik]

---

ROOT Version: 6.18/00
Platform: Linux (Manjaro)

---

Built ROOT from source (It was working fine till the last time I tested it which wasn’t so many days ago so something else might have updated to cause incompatibilities?)

I get the following logs when trying to import ROOT. Strangely enough, even with these error logs, ROOT seems to be working fine.

[reik@reik-msi ~]$ root -l
grep: stack overflow
ERROR in cling::CIFactory::createCI(): cannot extract standard library include paths!
Invoking:
  LC_ALL=C c++  -O3 -DNDEBUG -xc++ -E -v /dev/null 2>&1 >/dev/null | awk '/^#include </,/^End of search/{if (!/^#include </ && !/^End of search/){ print }}' | GREP_OPTIONS= grep -E "(c|g)\+\+"
Results was:
grep: stack overflow
With exit code 512

What is the output of the command below on your machine?

$ LC_ALL=C c++ -O3 -DNDEBUG -xc++ -E -v /dev/null 2>&1 >/dev/null

Manjaro had a repo release cycle yesterday and after the update, I do not get the error log again. I think it was a broken gcc update or something from Manjaro.

Here is the log just in case -

[reik@reik-msi ~]$ LC_ALL=C c++ -O3 -DNDEBUG -xc++ -E -v /dev/null 2>&1 >/dev/null
