STM32F4xx alternate configuration SPI1 issues

Hello Everyone,

I was just wondering if anyone has seen this, I have seen this only referenced on one website.  I have SPI1 on a STM32F415 configured as 

  PA7   ------> SPI1_MOSI
  PB3   ------> SPI1_SCK
  PB4   ------> SPI1_MISO 

Which works fine until i configure PE3, as soon as I do that the SPI1 stops working if I comment the following out it will work again.

  /*Configure GPIO pins : PE3  */
//  GPIO_InitStruct.Pin = GPIO_PIN_3;
//  GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
//  GPIO_InitStruct.Pull = GPIO_NOPULL;
//  GPIO_InitStruct.Speed = GPIO_SPEED_FAST;
//  HAL_GPIO_Init(GPIOE, &GPIO_InitStruct);

I haven't seen no errata about it, am I the only one seeing this?

Thanks,
George
