This reminds me of:

  https://issues.guix.gnu.org/46212

and indeed:

--8<---------------cut here---------------start------------->8---
$ guix build flightgear -n --no-grafts

The ‘NarSize’ field is still broken on ci.guix:

--8<---------------cut here---------------start------------->8---
$ wget -qO - https://ci.guix.gnu.org/ashmi6vr9d0k03z9q6ncbb2wf36p9nyk.narinfo 
|grep Size
FileSize: 1876560180
FileSize: 1715771086
FileSize: 1753645085
NarSize: 18446744072093825552
$ wget -qO - 
https://bordeaux.guix.gnu.org/ashmi6vr9d0k03z9q6ncbb2wf36p9nyk.narinfo |grep 
Size
FileSize: 1715771086
NarSize: 2679241232
--8<---------------cut here---------------end--------------->8---

and again the database on berlin has a negative size:

--8<---------------cut here---------------start------------->8---
$ sudo sqlite3 /var/guix/db/db.sqlite
SQLite version 3.32.3 2020-06-18 14:00:33
Enter ".help" for usage hints.

--8<---------------cut here---------------end--------------->8---

[Time passes…]

OK, this one is now fixed by commit
1eb40a6dc4917f5a2e915f8b31b750dba3d378c6m, which means you now get:

--8<---------------cut here---------------start------------->8---
$ guix build flightgear --no-grafts  -n
1,715.8 MB would be downloaded:
   /gnu/store/ashmi6vr9d0k03z9q6ncbb2wf36p9nyk-flightgear-2020.3.11
guix build: warning: at least 18,446,744,072,093.8 MB needed but only 4,753.4 
MB available in /gnu/store
--8<---------------cut here---------------end--------------->8---

Fun, no?  :-)

Also, after substitution, the size in the store database would be the
wrong one, so ‘guix size’ would keep telling you it’s this big.  Not
great but harmless as the nar size is used for UI purposes only.
