I have the following declarations (non relevant members left out)

typedef void __fastcall (__closure *TUpdateGuardFunc) (void);
 
class PACKAGE SUpdater
{
protected:
  TUpdateGuardFunc FEndFunc;
 
  __fastcall SUpdater (void);
 
public:
  __fastcall  SUpdater (TUpdateGuardFunc beginFunc, TUpdateGuardFunc endFunc);
  __fastcall  SUpdater (TStrings *strings);
  __fastcall  SUpdater (TCollection *collection);
  __fastcall ~SUpdater (void);
};

and another class

class PACKAGE TLicTranslations : public TLicCustomTextFile
{
...
public:
 
   virtual int   __fastcall  Load (TStrings *source);
 
          void  __fastcall  DisableUpdates (void);
          void  __fastcall  EnableUpdates (void);
          void  __fastcall  Push (UnicodeString const &documentTag, UnicodeString const &languageId);
          void  __fastcall  Push (UnicodeString const &documentTag);
          void  __fastcall  Push (void);
          void  __fastcall  Pop (void);
 
};

In member function Load, I have the following

  SUpdater updater    (DisableUpdates, EnableUpdates);
  SUpdater restoreIds (Push, Pop);

The first of these lines compiles without a problem, but the second one gives an error. With the code as shown above, the error is E2285 Could not find a match for 'SUpdater::SUpdater(void (_fastcall TLicTranslations::*)(const UnicodeString &,const UnicodeString &),void)'

When I change it into

  SUpdater updater    (DisableUpdates, EnableUpdates);
  SUpdater restoreIds ((TUpdateGuardFunc) &Push, Pop);

the error changes into E2336 Pointer to overloaded function 'TLicTranslations::Push' doesn't match 'TUpdateGuardFunc'

My question is why?

The signatures for DisableUpdates and EnableUpdates are exactly the same as for Push and Pop. The only difference is that for Push I have two more overloaded variants. According to

http://webcache.googleusercontent.com/search?q=cache:AO9sGvPv6aAJ:http://en.cppreference.com/w/cpp/language/overloaded_address%2Bc%2B%2B+get+address+overloaded+function&hl=en&gbv=1&ct=clnk

the compiler should pick the overloaded variant that matches the signature. So, why isn't the signature for void __fastcall Push (void) a match, while it is a match for void __fastcall DisableUpdates (void)
