You are right. This is a bug in FriCAS itself. I did not change "I" to "%i"
when I tried it before.
Should I then close the bug report I opened in sagemath about this in this
case? Or if you like to close it yourself, that is fine also.
Thanks

Actually, this is a proper bug in FriCAS, because the translation of your
integral is
integrate((%i*a*tan(d*x + c) + a)*sec(d*x + c)^10, x)
(note the "%i" instead of "I", which is FriCAS' complex unity, "I" is just
any other variable for FriCAS)
The result of the above integral is

fyi;
I noticed many more FriCAS integrals tests fail in sagemath 8.9 due to
still some interface issue between Sagemath and FriCAS. This affects result
of FriCAS integration test.
Entered new bug here https://trac.sagemath.org/ticket/29043
"NotImplementedError: the translation of the FriCAS
