It looks sensible, shutdownHaskell() is the last thing the
RTS calls before exiting. Could it be that fflush() is failing
since stdout hasn't been used? Does the following work OK

#include <stdio.h>

int
main()
{
  fflush(stdout);
  return 0;
}

if it does, what about this

#include <stdio.h>

int
main()
{
  char msg[]="Hello";

  write(1,msg,sizeof(msg)-1);
  fflush(stdout);
  return 0;
}
