Even shorter:
struct ErrmsgWindow
{
virtual ~ErrmsgWindow()
{
extern int _switch_mode_errorstr;
_switch_mode_errorstr = 42;
}
};
void ShowErrorMessage(void)
{
ErrmsgWindow w;
}
The problem appears with r151360, which is the merge of free_lang_data.
A quick glance reveals that the problem is that somehow the inlining of
__deleting_dtor into __comp_dtor doesn't correctly adjust the DECL_CONTEXT
of the _switch_mode_errorstr decl.
As this can't be reproduced with a similar setup just involving normal
functions (not dtors) I would assume that the special handling of clones
and how they are produced from each other is broken.
