Version: (using KDE KDE 3.4.2) Installed from: Gentoo Packages While editing a long (>11000 lines) c++ source file, I was hitting "reformat source". Kdevelop crashed, all changes made to the source file were lost (annoying). This happened using kdevelop 3.2.90. The problem can be repeated easily. If you need the source (~1 MB), tell me. Using host libthread_db library "/lib/tls/libthread_db.so.1".

This is probably a kate bug
without any file to reproduce, no chance, perhaps already fixed, perhaps still there hidden in the dark
Created attachment 12812 [details] File which crashes kdevelop if auto-reformatted.
A file to reproduce, a chance, not fixed in 3.2.91 using kde 3.4.91, not hidden in the dark
k, thx for the file :) Now my remaining problems are: the KDE 3.4 version of KDevelop I have from KUbuntu has no such button, as the whole indentation stuff is missing and my 3.5 branch doesn't compile, as I have other berkley libs around, back to KDevelop, if they can give me more feedback, will look again.
KDevelop just calls KTextEditor::EditInterface::setText(). See http://websvn.kde.org/tags/KDE/3.4.2/kdevelop/parts/astyle/astyle_part.cpp?rev=436917&view=markup, AStylePart::beautifySource(). I guess it is conceivable that the astyle manipulation of the string corrupts it and katepart is fed broken input, but I can't test it at the moment.
This is indeed a katepart bug, and it has been fixed in revision 554150. *** This bug has been marked as a duplicate of 127928 ***
