Title: Infinite recursion when loading plugins leading to codeblocks crash.
Post by: Anon5710 on October 09, 2017, 04:15:50 pm: Hello,

I'm using codeblocks as an editor, using CENTOS7 as OS.
For some irritation unknown reason my installation stopped working today.
Around the same time, i was using to much space in my /home folder. (limited to 2 gb here :( )
I have cleared some old files, and I should have more then enough room now.

Whatever I do, codeblocks will hang a minute or so after start up.
If I look at the strace output, I'm seeing infinite symbolic link traversing :

stat("/sys/bus/cpu/devices/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu6/node0/memory147/subsystem/devices/memory246", 0x7ffd0e078710) = -1 ELOOP (Too many levels of symbolic links)
stat("/sys/bus/cpu/devices/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu0/node0/cpu6/node0/memory147/subsystem/devices/memory247", 0x7ffd0e078710) = -1 ELOOP (Too many levels of symbolic links)

As far as I'm aware this recursive symbolic linking is normal. (Other machines are setup like this to)
If i startup with --safe-mode, there is no crash and I can continue working. (without all the plugins tough ... )

I have tried :

1) clean the .codeblocks directory in /home/user/
2) uninstall and re-install all the packages. codeblocks.x86_64, codeblocks-contrib.x86_64, codeblocks-contrib-libs.x86_64 codeblocks-libs.x86_64

Any other things I can do to get this working again ?

This version of C::B is too old, and can you try a nightly version? Since the bugs may already fixed in the recent nightly build versions. Thanks.

Post by: oBFusCATed on October 09, 2017, 08:47:15 pm: Yep, this should be fixed in the 16.01 (not 100% sure) or night builds. If it is not then we need a backtrace to see where the recursion is starting.

Post by: Anon5710 on October 11, 2017, 03:27:05 pm: I have updated to the last version, while this specific infinite recursion is not occurring anymore.
Codeblocks is hanging on something else, again only when i run in normal mode. In safe mode this does not happen.

How should i go about providing a stacktrace ?

Post by: oBFusCATed on October 12, 2017, 09:23:58 am: The steps are something like:
1. install all debug info packages related to cb
2. install gdb
3. run codeblocks under gdb - gdb /usr/bin/codeblocks
4. what for the hang
5. ctrl-c
6. thread apply all bt

And send us the output from gdb.
