Hello, I have problem with TIdEncoderMIME component, when I create it dynamically. When I put it on form everything works fine. I found that CodingTable is null, probably Indy bug. I tried updating Indy component, but there is problem as well (The procedure entry point @Idheadercoderutf@initialization$qqrv could not be located in the dynamic link library IndyProtocols150.bpl). Can anyone help me?

        Code snippet
	TIdEncoderMIME *encoderPtr = new TIdEncoderMIME(NULL);
	String result = encoderPtr->Encode(String("test")); //access violation (CodingTable is null)
	delete encoderPtr;

C++ Builder XE Version 15.0.3953.35171 (with update 1)

It is not a bug in Indy, it is actually a bug in C++Builder itself.  The 
bug was addressed 3 years ago in Indy 10.5.8 SVN rev 4652 with the introduction 
of the WORKAROUND_INLINE_CONSTRUCTORS define in IdCompilerDefines.inc, which 
is commented as follows:

{code}
{$IFDEF CBUILDER}
  // When generating a C++ HPP file, if a class has no explicit constructor
  // defined and contains compiler-managed members (xxxString, TDateTime,
  // Variant, DelphiInterface, etc), the HPP will contain a forwarding
  // inline constructor that implicitally initializes those managed members,
  // which will overwrite any non-default initializations performed inside
  // of InitComponent() overrides! In this situation, the workaround is to
  // define an explicit constructor that forwards to the base class constructor
  // manually.
  {$DEFINE WORKAROUND_INLINE_CONSTRUCTORS}
{$ENDIF}
{code}

Indy does not use the IdHeaderCoderUTF unit anymore, it was replaced with 
the IdHeaderCoderIndy unit.  Any external packages that were compiled against 
the older Indy packages will need to be recompiled accordingly.
