To be honest, I don't know what some of these bug fields mean (triplet??), so
if you need more info please let me know.
I am trying to use precompiled headers to speed up my development time when
using wx-widgets. All of my source files crash when attempting to compile any
of them
Header file
---
$cat wxprec-proxy.h
#ifndef WXPREC_PROXY_H
#define WXPREC_PROXY_H
//This file is a workaround to a bug as
//described in GCC bugzilla (id 13675)
//BUG: #including a precompiled header more than once in the same unit fails
#include wxprec.h
#endif
---
$cat wxprec.h
#include wx/wx.h
#include wx/image.h
---
The segfault happens *every time* I use precompiled headers (I haven't tested
between source files yet)
wx-config output:
$wx-config --cflags
-I/usr/lib/wx/include/gtk2-unicode-release-2.8 -I/usr/include/wx-2.8

wxsimple header:
$ cat wxsimple.h
#infdef WXSIMPLE_H
#define WXSIMPLE_H
