Full terminal output as far as I can scroll back
I was trying to get a compiler with support for c++20, but I'm working on a
university computer so I have no sudo rights. Easiest solution seemed to build
g++10 or newer from source, so I did exactly that, following the tutorial on
https://gcc.gnu.org/install/
I've downloaded it from this mirror:
http://mirror.koddos.net/gcc/releases/gcc-11.2.0/ which is marked as an
official mirror on this page: https://gcc.gnu.org/mirrors.html
Due to space concerns, I only installed the c++ component
('--enable-languages=c++') and did the lean bootstrap ('make bootstrap-lean'),
otherwise I have not deviated from the default commands recommended to be run.
I did have to restart the bootstrap once, as the variable `CPLUS_INCLUDE_PATH`
was already set to a different value, resulting in the crash described in
#61427. I `unset` the variable, and ran the same command again. This time, the
terminal showed the following error:
```
cc1: internal compiler error: in fail_formatted, at selftest.c:63
0x24d14f5 selftest::fail_formatted(selftest::location const&, char const*, ...)

0x12e8ad5 toplev::run_self_tests()
../../gcc-11.2.0/gcc/toplev.c:2265
```
To reiterate, the exact command I ran was `make bootstrap-lean`, while inside
the objdir
The entire output as far as my terminal still shows it, is included as an
attachment. My $HOME on this pc is `/vol/s1935534`.
Running `gcc -v` gave the following output:

I have googled for this error, but the only other bug even mentioning the
`fail_formatted` function is #81101, which appears unrelated to building gcc
from source.
If any additional information is required,
