Cube L4 V1.13.0 LL__RCC_DeInit() failed in release

[laurentwawrzyniak9]

I use Atollic TrueSTUDIO v9.0.1 for a STM32L496RG project.

I use the LL_RCC_DeInit() function and have an issue when activation of Optimisation option -Ofast or -O3 .

To fix the issue I had to add the key word volatile (see code below).

ErrorStatus LL_RCC_DeInit(void)
{
  // uint32_t vl_mask;    // RCC register not changed when opitimzation -Ofast or -O3
  volatile uint32_t vl_mask;    //FIX to run with opitimzation -Ofast or -O3
 
  /* Set MSION bit */
  LL_RCC_MSI_Enable();
