Perhaps you should buffer the text passed to SDL? Something like the 
following:

// Do this once in a constructor or globally
char* renderedTextBuffer = new char[1024];

// Do this to render text
if (value.length > renderedTextBuffer.length) {
   renderedTextBuffer = new char[value.length];
}
renderedTextBuffer[0 .. value.length] = value;
renderedTextBuffer[value.length] = 0;
RenderText(renderedText);

This is effectively what toStringz() does, but it won't allocate memory 
with every render.
