After some struggle, build sagemath with maxima 5.47 upstream.
Could someone see if they get same error I see on this one example?

The same integrate command does not give this error the system maxima (also
version 5.47) (but it does not evaluate, but no exception):

All on Linux,
Why this gives exception when calling maxima from sage but not when calling
maxima directly? Is there something I can do to verify that maxima build
by sagemath internally is build correct? I saw no errors at all during the
build: Here is the maxima build by sagemath:
