STM32H5 internal compiler error

[dojyorin]

Details

Compilation fails with "internal compiler error: Segmentation fault" during compilation.

Repeatability

• OS: Windows 11 x64
• Arduino Version: Arduino-CLI 0.34.2
• Use from: VSCode Arduino Extension
• STM32duino Version: 2.6.0
• Target Board: Nucleo-H563ZI

The problem occurs even if I compile an blank project.

void setup(){}
void loop(){}

Cause

After some research I don't know why, replaced DMA_CLBAR_LBA to 0 in below, compilation was successful.

Arduino_Core_STM32/system/Drivers/STM32H5xx_HAL_Driver/Src/stm32h5xx_hal_dma_ex.c

Line 4122 in 1ee0a03

if (temp != ((uint32_t)ref & DMA_CLBAR_LBA))

if (temp != ((uint32_t)ref & 0))

The current value of DMA_CLBAR_LBA is 0xFFFF0000.

Hi @dojyorin
I was not able to reproduce on Windows 10 nor with Linux.
Anyway, it seems already reported to STMicroelectronics GH:
STMicroelectronics/stm32u5xx-hal-driver#5
Reading this issue, you will be redirected to some bugzilla.
It is linked to gcc:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108340

So I close it as not related to the core and will be fixed within next arm none eabi gcc toolchain update.

Maybe this issue could interest @ilg-ul. At least for information.

Thank you @fpistm, I'll keep in mind that there is an issue, but there is not much we can do, we'll wait for Arm to make a new release.

Welcome, as stated it is more FYI than expecting support. I know you can't do nothing 😉
