Hi, I set up a small example to try to reproduce this problem: https://salsa.debian.org/paolog-guest/hello-doxygen/-/commits/368577
Note: I set CALL_GRAPH = YES in Doxyfile. Call graphs are generated fine for me on buster with doxygen 1.8.13-10 (see attachment). I'll close this bug unless someone has any objections. Paolo
