Re: Infinite backtrace of wxapp_poll_fun() while sending on socket from a thread to another [SOLVED]

@DavidHart, for Sure I do this. ----------------------- I found the issue, both components tries to Initialize Wx library using different function. This led to this strange behavior. I solved it by adding a condition checking if `wxTheApp` is NULL or no to allow the second initialization. ----------...

Re: Infinite backtrace of wxapp_poll_fun() while sending on socket from a thread to another [SOLVED]

Hi, It looks like you are using wx-2.8. Did you try to update to 3.0/3.1? It would also be nice to know where it crashes - produce a debug build of wx and your application (with symbols). Thank you. Upgrading to Wx 3.0 is a dream, but it's not currently possible. Debugging got me that it always cra...

Infinite backtrace of wxapp_poll_fun() while sending on socket from a thread to another [SOLVED]

We have two components that run in separate processes fine and communicates over TCP socket. We decided to merge both, that each component runs in a different thread and still communicates on the same TCP socket. When using batch mode, it works great. But when launch our GUI main frame it crashes wi...

Re: Wxwidget 2.8 - wxPostEvent crashes

Looking at the glib source, there are a few occasions where malloc() calls malloc_printerr() with an error message. It would have been nice to know which one it was in this case. https://sourceware.org/git/?p=glibc.git;a=blob;f=malloc/malloc.c;h=7889fb19613c8d2e16612e17ae73cd65e72b16b8;hb=8e448310d...

Re: Wxwidget 2.8 - wxPostEvent crashes

Did you also use the deep copy in the SetMessage* methods? In case of using C++ strings, the answer is No. But currently with C-strings, yes. I will make a trial of C++ strings with deep copying in `SetMessage` and Custom Copy Constructor. Can you find out which message malloc_printerr() is trying ...

Re: Wxwidget 2.8 - wxPostEvent crashes

@DavidHart, Here is the original copy constructor CustomGUIMessageEvent::CustomGUIMessageEvent(const CustomGUIMessageEvent& rOther) : wxNotifyEvent(rOther) , m_strMessage(rOther.m_strMessage) , m_strMessageTitle(rOther.m_strMessageTitle) { } I made the following trials 1. replacing ` m_strMessag...

Re: Wxwidget 2.8 - wxPostEvent crashes

Ok, that code looks fine. I checked the code for AddPendingEvent() in wx 2.8.12, the list of pending events is protected with a critical section, so that should be safe, too. As the assert happens in malloc(), is it possible that you just run out of memory? Did you check the memory usage of your ap...

Re: Wxwidget 2.8 - wxPostEvent crashes

Did you override the Clone() method in CustomGUIMessageEvent? If no: You have to. And make sure to create deep copies of the strings. If yes: Please show the code. Yes I did, #ifndef CUSTOM_GUI_MESSAGE_EVENT #define CUSTOM_GUI_MESSAGE_EVENT #include <wx/event.h> class CustomGUIMessageEvent: public ...

Wxwidget 2.8 - wxPostEvent crashes

[*]I've a huge multi-threaded app that utilizes events to update the GUI. So with a custom Event, wxPostEvent crashes with the following log : #0 0x00007ffff5464885 in raise () from /lib64/libc.so.6 #1 0x00007ffff5465e61 in abort () from /lib64/libc.so.6 #2 0x00007ffff54a587f in __libc_message () fr...
