The issue is with the new __mingw_*printf functions that were added.
Using this code:

#include <windows.h>
#include <stdio.h>

int main(void)
{
  WCHAR test[20], teststr[4096], tmp[4096];

  wcscpy(test, TEXT("test"));
  swprintf(teststr, TEXT("This is a %s"), test);
  swprintf(tmp, TEXT("%s - %d | %s - %d"), test, wcslen(test),
teststr, wcslen(teststr));

  MessageBox(GetDesktopWindow(), tmp, L"Test", MB_OK | MB_TOPMOST);

  return 0;
}

compiled via:

i686-w64-mingw32-g++ -U__USE_MINGW_ANSI_STDIO -DUNICODE test.cpp -o test

all is good.  However, if you compile the code via:

i686-w64-mingw32-g++ -D__USE_MINGW_ANSI_STDIO -DUNICODE test.cpp -o test

you will see the issue I am encountering.

Cheers,

Chris
