STM32CubeMX 4.7.1 code generation issue

Generating code from STM32CubeMX 4.7.1 (for STM32F072RBTx controller) messes up USER sections of stm32f0xx_hal_msp.c.

For instance, USER CODE ''TIM2_MspInit 0'' and ''TIM3_MspInit 0'' of function HAL_TIM_Base_MspInit are copied into the same sections of function HAL_TIM_PWM_MspInit. So, original code

void HAL_TIM_PWM_MspInit(TIM_HandleTypeDef* htim_pwm)
{
GPIO_InitTypeDef GPIO_InitStruct;
if(htim_pwm->Instance==TIM2)
{
/* USER CODE BEGIN TIM2_MspInit 0 */
/* USER CODE END TIM2_MspInit 0 */
/* Peripheral clock enable */
__TIM2_CLK_ENABLE();
/**TIM2 GPIO Configuration 
PA1 ------> TIM2_CH2
PA2 ------> TIM2_CH3
PA3 ------> TIM2_CH4
PA5 ------> TIM2_CH1 
*/
GPIO_InitStruct.Pin = GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3|GPIO_PIN_5;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;
GPIO_InitStruct.Alternate = GPIO_AF2_TIM2;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
/* USER CODE BEGIN TIM2_MspInit 1 */
/* USER CODE END TIM2_MspInit 1 */
}
else if(htim_pwm->Instance==TIM3)
{
/* USER CODE BEGIN TIM3_MspInit 0 */
/* USER CODE END TIM3_MspInit 0 */
/* Peripheral clock enable */
__TIM3_CLK_ENABLE();
/**TIM3 GPIO Configuration 
PB0 ------> TIM3_CH3
PB1 ------> TIM3_CH4
PB4 ------> TIM3_CH1
PB5 ------> TIM3_CH2 
*/
GPIO_InitStruct.Pin = GPIO_PIN_0|GPIO_PIN_1|GPIO_PIN_4|GPIO_PIN_5;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_LOW;
GPIO_InitStruct.Alternate = GPIO_AF1_TIM3;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
/* USER CODE BEGIN TIM3_MspInit 1 */
/* USER CODE END TIM3_MspInit 1 */
}
}

after code generation becomes

void HAL_TIM_PWM_MspInit(TIM_HandleTypeDef* htim_pwm)
{
GPIO_InitTypeDef GPIO_InitStruct;
if(htim_pwm->Instance==TIM2)
{
/* USER CODE BEGIN TIM2_MspInit 0 */
Applic_TIM_PWM_MspInit(htim_base);
/* USER CODE END TIM2_MspInit 0 */
/* Peripheral clock enable */
__TIM2_CLK_ENABLE();
/**TIM2 GPIO Configuration 
PA1 ------> TIM2_CH2
PA2 ------> TIM2_CH3
PA3 ------> TIM2_CH4
PA5 ------> TIM2_CH1 
*/
GPIO_InitStruct.Pin = GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3|GPIO_PIN_5;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;
GPIO_InitStruct.Alternate = GPIO_AF2_TIM2;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
/* USER CODE BEGIN TIM2_MspInit 1 */
/* USER CODE END TIM2_MspInit 1 */
}
else if(htim_pwm->Instance==TIM3)
{
/* USER CODE BEGIN TIM3_MspInit 0 */
Applic_TIM_PWM_MspInit(htim_base);
/* USER CODE END TIM3_MspInit 0 */
/* Peripheral clock enable */
__TIM3_CLK_ENABLE();
/**TIM3 GPIO Configuration 
PB0 ------> TIM3_CH3
PB1 ------> TIM3_CH4
PB4 ------> TIM3_CH1
PB5 ------> TIM3_CH2 
*/
GPIO_InitStruct.Pin = GPIO_PIN_0|GPIO_PIN_1|GPIO_PIN_4|GPIO_PIN_5;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_LOW;
GPIO_InitStruct.Alternate = GPIO_AF1_TIM3;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
/* USER CODE BEGIN TIM3_MspInit 1 */
/* USER CODE END TIM3_MspInit 1 */
}
}

where

lines in yellow background

come from function HAL_TIM_Base_MspInit

void HAL_TIM_Base_MspInit(TIM_HandleTypeDef* htim_base)
{
GPIO_InitTypeDef GPIO_InitStruct;
if(htim_base->Instance==TIM2)
{
/* USER CODE BEGIN TIM2_MspInit 0 */
Applic_TIM_PWM_MspInit(htim_base);
/* USER CODE END TIM2_MspInit 0 */
/* Peripheral clock enable */
__TIM2_CLK_ENABLE();
/**TIM2 GPIO Configuration 
PA1 ------> TIM2_CH2
PA2 ------> TIM2_CH3
PA3 ------> TIM2_CH4
PA5 ------> TIM2_CH1 
*/
GPIO_InitStruct.Pin = GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3|GPIO_PIN_5;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;
GPIO_InitStruct.Alternate = GPIO_AF2_TIM2;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
/* USER CODE BEGIN TIM2_MspInit 1 */
/* USER CODE END TIM2_MspInit 1 */
}
else if(htim_base->Instance==TIM3)
{
/* USER CODE BEGIN TIM3_MspInit 0 */
Applic_TIM_PWM_MspInit(htim_base);
/* USER CODE END TIM3_MspInit 0 */
/* Peripheral clock enable */
__TIM3_CLK_ENABLE();
/**TIM3 GPIO Configuration 
PB0 ------> TIM3_CH3
PB1 ------> TIM3_CH4
PB4 ------> TIM3_CH1
PB5 ------> TIM3_CH2 
*/
GPIO_InitStruct.Pin = GPIO_PIN_0|GPIO_PIN_1|GPIO_PIN_4|GPIO_PIN_5;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_LOW;
GPIO_InitStruct.Alternate = GPIO_AF1_TIM3;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
/* USER CODE BEGIN TIM3_MspInit 1 */
/* USER CODE END TIM3_MspInit 1 */
}
}

By the way, after code generation, function HAL_TIM_PWM_MspInit does not compile anymore, because of unknown symbol htim_base.
