[lldb-dev] lldb crash while debugging wxWidgets application that was built with g++

[Eran Ifrah]

Hi,

While debugging a real world application (codelite) I placed a breakpoint
in the 'OnAbout' function
attempting to view any of the local variables resulted in crash, see below:

Process 24146 stopped
* thread #1: tid = 24146, 0x00000000006667f6
codelite`clMainFrame::OnAbout(this=0x000000000215f5c0,
(null)=0x00007fffa6fd2640) + 66 at frame.cpp:1794, name = 'codelite', stop
reason = step over

   1795     dlg.SetInfo(mainTitle);
   1796     dlg.ShowModal();
   1797 }
(lldb) p dlg
error: libwx_gtk2u_unofficial_core-3.0.so.0 DWARF DIE at 0x030ac4cc for
class 'wxSizer' has a base class 'wxClientDataContainer' that is a forward

Please file a bug against the compiler and include the preprocessed output

Segmentation fault

>From the segfault message, I understand that this is a bug with gcc
Still, is there a way to suppress this error by telling lldb to silently
ignore this? ( I prefer it to display nothing instead of crashing and
taking down codelite with it )

Thanks
