I could not reproduce this issue. What is cedet-load-path?

One work around is to enable stickyfunc-mode via major mode hooks. E.g., after commenting out the last line above `global-semantic-stickyfunc-mode’, stickyfunc mode can be enabled in C mode with the following hook:

In fact, whereas stickyfunc-mode works with C code, it seems not to have worked with Lisp for a while now (i.e., prior to removal of the `default-FOO’ variables). Obviously it would help to identify the breaking commit, but I’m not even sure what time frame to examine.

Should I be looking at CEDET code, or might the problem be of a more generic nature that could be affecting other code that I haven’t come across yet? Once enough information has been gathered, a bug report will be submitted. Thank you!
