>Description:
The ICE does not happen when the forward declaration of SCKeyEntry is
replaced by the definition.
>How-To-Repeat:
$ cat int_for_mode.cc
class ShortCutKey;
struct SCKeyEntry;
class SCKeyTable {
public:
  void AddSCKey(unsigned long sym, unsigned int modifier, int fn);
};
extern SCKeyEntry scMenuKey[];
extern const int MenuKeyNum;
extern SCKeyTable* menuKey;
struct SCKeyEntry {
  unsigned long sym;
  unsigned int mod;
  int func;
};
void InitQvwm()
{
  menuKey->AddSCKey(scMenuKey[0].sym, scMenuKey[0].mod, scMenuKey[0].func);
}
