Even more strange (I was hoping to see some munging of query params
due to url rewriting or some such). But with identical input, you
should get identical output (ctx->repo should point at the correct
repo-struct in all the above cases), so I assume that ctx->repo
somehow becomes NULL after the call to cgit_get_repoinfo(), but only
when initialized via cgit_parse_url().

Could you try running cgit under gdb to find the culprit? E.g:

$ PATH_INFO=fsmenu gdb ./cgit
(gdb) break cgit_parse_url
(gdb) run
