Crash with batch build on linux

[BlueHazzard]

Hi, i use the command line on my headless server to build codeblocks projects...
I can not reproduce this 100% but it occurs 1 in 6 times: I get a crash "call of pure virtual function" on the finish of a compilation.
This is the backtrace:

Any ideas how to debug this?

[oBFusCATed]

Run cb from cb and debug it with gdb. Just edit the program arguments and/or work folder.

Most probably the text logger is already deleted when clear is called.

[BlueHazzard]

Wasn't there a ticket or a forum post about the log panel with a fix lately?
I can not find it anymore...

[Miguel Gimenez]

Ticket 738:

https://sourceforge.net/p/codeblocks/tickets/738/

I added a check about batch building before clearing the log, but it wasn't accepted.

[oBFusCATed]

@Miguel: If you look at the backtrace you'll see that this for the clear call is not nullptr, so your fix would probably be unhelpful in this case.

[Miguel Gimenez]

While investigating the crash I found this code snippet (not related directly to the crash) in compilergcc.cpp:

Code Select Expand


        if (!Manager::IsBatchBuild())
        {
            CodeBlocksLogEvent evt(cbEVT_REMOVE_LOG_WINDOW, m_pLog);
            Manager::Get()->ProcessEvent(evt);
        }

        {
            // TODO: This is wrong. We need some automatic way for this to happen!!!
            LogSlot &listSlot = logManager->Slot(m_ListPageIndex);
            delete listSlot.icon;
            listSlot.icon = nullptr;

            LogSlot &slot = logManager->Slot(m_PageIndex);
            delete slot.icon;
            slot.icon = nullptr;
        }

        m_pLog = 0;


The log window removal is made conditionally, but the nullifying of m_pLog always happens. Is this correct?

[BlueHazzard]

While investigating the crash I found this code snippet (not related directly to the crash) in compilergcc.cpp:

So you can reproduce the crash?

[Miguel Gimenez]

Didn't try. I haven't used batch building since ticket 738, and the crash I got is fixed in my local copy.

Post the full command you use, if I get time I'll check.

sadly the backtrace of the free is not really helpful

{edit] the command line:

Code Select Expand

output30/run.sh --target=All --no-splash-screen --build CodeBlocks_wx30-unix.workspace
you probably have to run it a view times until you trigger it...

[oBFusCATed]

Rebuild everything with -fno-omit-frame-pointer.

[BlueHazzard]

By everything you mean also wxWidgets? Because codeblocks is build with -fno-omit-frame-pointer

[oBFusCATed]

The whole system would be best, but yes building wx with -fno-omit-frame-pointer improves backtraces produced by asan.

[oBFusCATed]

But you don't need asan for tracking this problem just place a breakpoint on ~TextCtrlLogger and you'll find who is deleting it.

[debug]SUMMARY: AddressSanitizer: heap-use-after-free /home/codeblocks/codeblocks/src/sdk/loggers.cpp:165 in TextCtrlLogger::Clear()

This output is somehow more useful then the debugger or not? Anyway, i wanted to learn how to use the address sanitizer and now i have a chance to use it

The question now is, why is the window destroyed before the application exits?

[Miguel Gimenez]

The question now is, why is the window destroyed before the application exits?

Because in batch mode it is not needed anymore. The crash is due to the destruction of the log window before closing the workspace, as there is a call to ClearLog() in the workspace closing event.

Solutions:
  - Use --no-batch-window-close in the command line call
  - Destroy the window after closing the workspace, not before
  - Use my patch in ticket 738
  - Mark the window as destroyed and don't call ClearLog() if it is marked
  - Remove the call to ClearLog() from the workspace closing event
