Issue created by Sebastian Huber: https://gitlab.rtems.org/rtems/rtos/rtems/-/work_items/5703
The link scripts of `av5282`, `mcf5235` and `mcf5329` collect the exception frames without `KEEP()`, so `--gc-sections` removes the terminating zero word which `crtend.o` contributes. `crtbegin.o` gives `__register_frame_info()` the start of the table and the unwinder walks the entries until it finds a zero length. It never finds one, walks past the end and reads whatever follows, so every throw ends in a fatal exception. This description was created with Claude Code assistance. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/work_items/5703 You're receiving this email because of your account on gitlab.rtems.org.
