Could not find abbrev number 79 in CU at offset 0x0

When I try to debug my stm8s105k4 in VScode I get the following error message in the debug console:
Reading symbols from C:\Users\woutc\Documents\PlatformIO\Projects\IB3_test_NRF24.pio\build\stm8sblack\firmware.elf…
Dwarf Error: Could not find abbrev number 79 in CU at offset 0x0 [in module C:\Users\woutc\Documents\PlatformIO\Projects\IB3_test_NRF24.pio\build\stm8sblack\firmware.elf]

I use this in my platform.ini:
[env:stm8sblack]
platform = ststm8
board = stm8sblack
framework = spl
upload_protocol = stlinkv2
debug_tool = stlink

The program compiles and uploads successfully to the board.
I am using an stm8s105k4 breakout board paired with an st-link v2 (from China) on windows 11.
After asking help from someone who got it working in l Linux and searching on the internet I can’t figure out how to solve this.

Looks exactly like https://github.com/platformio/platform-ststm8/issues/44 to me, but only workarounds are known at the moment. May need an SDCC upgrade.

I cannot reproduce the fix anymore by exchanging the linking order between main and stm8_gpio. Will need to update the bug report and hope for SDCC people’s support. But as it stands, their latest snapshot of the compiler doesn’t even execute.
