I just tested it on my self-compiled system (ok ok slackware base but most is by now self-compiled), also geany. I do not seem to get any crashes at all whatsoever pressing Ctrl+F. I have not tried with the same configure line though, but perhaps the git variant should be tested.
By the way, is it possible to get a full stack trace of the segfault? (This is an open question, not to anyone in particular, just general)
