race bug !?

[Jean-Jacques Brucker]

100 % reproducible on my Debian, package version 5.1-2:



$ echo "dc30a6d79f3b47e310b8b9f5fbadba57" | tee >( xxd  -r -p | base64) 
| tee >(xxd  -r -p | basenc --base64url )
dc30a6d79f3b47e310b8b9f5fbadba57
3DCm1587R+MQuLn1+626Vw==
3DCm1587R-MQuLn1-626Vz0Vhw==


I first thought I missed something about base64url encoding, after hours 
or digging and digging documentation I tried :

$ echo "dc30a6d79f3b47e310b8b9f5fbadba57" | xxd  -r -p | basenc --base64url
3DCm1587R-MQuLn1-626Vw==


Those 4 extra characters "z0Vh" are quite disturbing :-/

Then I played more, cf. attachment.


$ LANG= bash --version
GNU bash, version 5.1.4(1)-release (x86_64-pc-linux-gnu)

Cheers,
