For the question about seeing which version of maxima is used by calculus
(through the ECL backend):
maxima_calculus.version()

The maxima command issue us caused by an incomplete SBCL upgrade and should
be already fixed. The Sage maxima interface for integration uses the ECL
backend so it's not affected by that issue.

I am on CachyOS Linux. I do not build anything from source anymore and just
use pacman package manager to install all software.
I installed sagemath using pacman a week ago and also installed maxima
5.47. Everything was working OK. maxima was working oK on its own also.
Last night, I did system update, and pacman updated maxima to the new
version of Maxima just released which is 5.48.
But due to SBCL problem with maxima (reported to Maxima), can't use maxima
directly from command line. It gives error. But I am able to call maxima
integrate from inside sagemath with no error.
So I am wondering now if when calling integrate with algorithm="maxima" .
if it is using 5.48 or some other version, may be linked internally inside
sagemath binary? When calling
sage: print(maxima.version())
from inside sagemath it gives same error I get from command line.
Is it possible the integrate command is still using maxima 5.48, but this
error does not affect this call?

My question again: is integrate command above using maxima 5.48 installed
on the system, even though maxima does not start from command line? Here is
