When trying to build the mpfs_icicle application example (synchronization, synchronization_blinky, smp/pi) the zephyr-sdk-0.15.0 does not complete the build but errors out with an incompatible ABI error. With zephyr-sdk-0.13.2 the application examples build without issues.
For example when trying to build the pi example with zephyr-sdk-0.15.0:
west build -p -b mpfs_icicle mpfs-applications/smp/pi -G "Eclipse CDT4 - Unix Makefiles"
Build fails at 93% Progress with the following errors:
