wxLogWindow Crash [SOLVED]

Do you have a typical platform dependent issue you're battling with ? Ask it here. Make sure you mention your platform, compiler, and wxWidgets version.

wxLogWindow Crash [SOLVED]

Post by heinermueller »

Hi All,

i am using wx 3.1.0 compiled under OSX 10.9
When i try to create a log window, wx crashes.
Sample code

Code: Select all

 wxLogWindow* wl = new wxLogWindow(nullptr,wxString());
It crashes here (textctrl_osx.cpp)

Code: Select all

#if wxOSX_USE_COCOA
    // under carbon everything can already be set before the MacPostControlCreate embedding takes place
    // but under cocoa for single line textfields this only works after everything has been set up
    GetTextPeer()->SetStringValue(str);
#endif
Is this a known issue? Is there a workaround? I create the log window in mywxapp::OnInit(),
is this too early?

Best regards,
Heiner

Hi,
Can you reproduce the problem in e.g. keyboard sample?

Thank you.

I used the minimal sample (hope that makes no difference) and there it works. I put it directly in the first line of OnInit()

This (minimal sample) works:

Code: Select all

bool MyApp::OnInit()
{
     wxLogWindow* wl = new wxLogWindow(nullptr,wxString());
    wl->Show();
    wxLogDebug("logging!");   
.....
}
This (my application) crashes:

Code: Select all

ool myApp::OnInit()
{
    wxLogWindow* wl = new wxLogWindow(nullptr,wxString());
.....
}
The difference is here:

Code: Select all

wxTextWidgetImpl * wxTextEntry::GetTextPeer() const
{
    wxWindow * const win = const_cast<wxTextEntry *>(this)->GetEditableWindow();
    return win ? dynamic_cast<wxTextWidgetImpl *>(win->GetPeer()) : NULL;
}
'win' exists but the dynamic cast fails. Any idea why?

I think i ran into a symbol visibility issue. Which settings do i have to change to solve that?

This is the system console output:
29/08/16 19:34:32,702 TestProgram: dynamic_cast error 2: One or more of the following type_info's has hidden visibility. They should all have public visibility. 12wxWidgetImpl, 19wxNSTextViewControl, 16wxTextWidgetImpl.
Why are the type infos in my application hidden but public in the minimal sample?

And i am linking statically to libwx_osx_cocoa_static.a -- i thought symbol visibility should be irrelevant when linking to static libraries?

I checked with nm (i am on osx) and this is the output. Nothing is marked hidden.

Re: wxLogWindow Crash

Post by heinermueller »

This is what i found in a very interesting blog entry about the topic:
To detect this insidious problem, if you're compiling with the 10.7+ linker, I recommend turning fatal_warnings on. If you're using the 10.6 linker, the nm method from before will work because the symbol will be marked non-external in the binary. If you're super-paranoid, you can run nm -om * | c++filt on all your .o files - object files where the visibility was hidden will report weak private external typeinfo where object files with default visibility will report weak external typeinfo (note that if you forget the -m flag on nm these two cases are indistinguishable).
And nm gives me something similar ( "private external typeinfo" not "weak private external typeinfo" )

Code: Select all

libwx_osx_cocoa_static.a:textentry_osx.o:          (undefined) external typeinfo for wxTextWidgetImpl
libwx_osx_cocoa_static.a:textctrl_osx.o: 000ad930 (__DATA,__const) private external typeinfo for wxTextWidgetImpl
libwx_osx_cocoa_static.a:textctrl_osx.o: 000ad950 (__TEXT,__const) private external typeinfo name for wxTextWidgetImpl
libwx_osx_cocoa_static.a:textctrl.o:          (undefined) external typeinfo for wxTextWidgetImpl

Re: wxLogWindow Crash

Post by heinermueller »

When i build the library with the (wx default setting) -fvisibility=hidden and -fvisibility-inlines-hidden i get this:

Code: Select all

grep "wxTextWidgetImpl" symbols_hidden_by_default_yes.txt | grep typeinfo 
libwx_osx_cocoa_static.a:textentry_osx.o:          (undefined) external typeinfo for wxTextWidgetImpl
libwx_osx_cocoa_static.a:textctrl_osx.o: 000ad930 (__DATA,__const) private external typeinfo for wxTextWidgetImpl
libwx_osx_cocoa_static.a:textctrl_osx.o: 000ad950 (__TEXT,__const) private external typeinfo name for wxTextWidgetImpl
Without -fvisibility=hidden and -fvisibility-inlines-hidden i get this:

Code: Select all

grep "wxTextWidgetImpl" symbols_hidden_by_default_no.txt | grep typeinfo 
libwx_osx_cocoa_static.a:textentry_osx.o:          (undefined) external typeinfo for wxTextWidgetImpl
libwx_osx_cocoa_static.a:textctrl_osx.o: 000ad930 (__DATA,__const) external typeinfo for wxTextWidgetImpl
libwx_osx_cocoa_static.a:textctrl_osx.o: 000ad950 (__TEXT,__const) external typeinfo name for wxTextWidgetImpl
Which one is correct?

Re: wxLogWindow Crash [SOLVED]

Post by heinermueller »

It turned out that the problem came from a linked-in dylib which linked statically against a different libstdc++, which was unaware of the typeinfos used elsewhere. So all dynamic_cast failed.
