I've done this a couple of times now here and can't reproduce this. Maybe this is specific to 64bit systems.
build from svn 24 march, this is not first crash when i replace guards in header, but can not reproduce it every time.
is your header big, or does it include lots of other files? I assume that the background parser is active while you change something in it which triggers the crash - but this is just a guess. @apaku: did you try with a small test header or with a real (big) header?
Small test header only, but as is visible from the dupe I closed shortly before there are at least two or three other ways of triggering it and one thing all reports have in common is a 64bit system. As I never had such a crash as far as I can remember and I only run 32bit systems that seemed like a plausible explanation.
Edit small file from real project, but include other not small generated headers.
Will probably be fixed for KDevelop 4.1 using the foreground lock.

works for me. Please try again with update Kate as there was a bug in it that left a dangling pointer in a smart range watcher list.

Unfortunately, the current master version of KDevelop does not work with KDE 4.5.1. It requires what will become KDE 4.5.2, or KDE 4.6. That's the reason for the crash.
