Bug 227116 (crash_close_40)

Can you reproduce this?

(In reply to comment #1)
> Can you reproduce this?

I can, it happens every time I close it.

Same bug on Ubuntu package:
kdevelop version: 4:3.9.98-0ubuntu1
OS: Ubuntu 10.04 (Lucid Lynx) ALPHA 2
kernel: 2.6.32-14-generic

Several files where open (at least five). Seems more likely to happen when more files are open.

Can you start+close kdevelop in valgrind, and send the valgrind log?

> Can you start+close kdevelop in valgrind, and send the valgrind log?

Could you give me the command line of what you want?
The output of "valgrind kdevelop" probably wouldn't be very useful.

*** Bug 234155 has been marked as a duplicate of this bug. ***

This happens everytime I close Kdevelop. I am using a beta version, so I expect
some things to still be sorted out. The only thing that I can think of is I
have the set of source files open in the editor when I exit. Nothing really
happens, the KDE Crash Reporting Assistant just shows up. All of my files that
I was working on are unaffected.
I tried again after closing all of my files that were open, and it still shows
up with the crash.
When I open Kdevelop without it already having files open (a blank window basically) then close this crash does not happen. It seems to only happen when Kdevelop opens with files already open in the workspace.

****** END with files open ******

please try again with the proper way to run kdevelop in valgrind (yes that sucks and is unintuitive but required for now...):

1) kdevelop --session
=> copy the HASH including the {} for the session you want to open
2) KDEV_SESSION=$THE_HASH valgrind kdevelop.bin

/me hopes you can reproduce it in valgrind, I tried many times without ever succeeding :-/

Good luck!

Wierd....  I tried to do the kdevelop --session and it came back and told me:

kdevelop: '<sessionId>' missing.
kdevelop: Use --help to get a list of available command line options.

It does this regardless of whether or not kdevelop is running beforehand. On the same note, so far I'm not getting the crash anymore, I did just now update to kernel 2.6.32.20.21, among about 40 other updates, so maybe that did the trick.

sorry, it must be --sessions (note the trailing s).

I just ran kdevelop  with --track-origins to hunt something else down, and shut down while it was parsing. There I got these messages, esp. the last one is interesting as it's related to this bug report (hopefully/maybe, at least it's also in itemRepository/Bucket).

Oh and setting to confirmed since I get this crash rather often on different systems, and so do others according to feedback on IRC.

Hmmmm, well when I try running kdevelop --sessions I get:

Available sessions (use '-s HASH' or '-s NAME' to open a specific one):

Hash                                    Name: Opened Projects

I'm guessing that the HASH you were talking about is supposed to be below the Hash word in this table, but nothing shows up there. I'll keep tinkering and see if I get any usable result.

Ah yeah because you never gave a session a name or have any open with some projects probably...

Anyways, I just checked and this works like a charm:

KDEV_SESSION=foo valgrind --track-origins kdevelop.bin

i.e. you can pass anything to the env-var.

Valgrind of kdevelop

Interesting side note... After I actually named my session (I had previously been working with an unnamed session) I cannot reproduce the error anymore. I've tried opening, editing, compiling, running, and everything else that I would normally do. So I wonder if it has to do with an unnamed session.

It does this too me with the latest KDevelop. 4.0 final, KDevPlatform 1.0 (Ubuntu 10.04 64-bit). I open up KDevelop, with a project already open, and I leave it open and do nothing for like 10 minutes, then close it, then it closes and crashes, it happens pretty consistently.

fixed for some time in KDevelop 4.1 branch (due to Apaku's changes regarding global statics), hence closing now.

If someone can reproduce it with 4.1, please reopen.
