Research direction
Start with the attached debug-30c93a.sh reproducer and debug-30c93a.c, then inspect build.log to confirm the AArch64 Clang 23.1.0_rc2 ICE and its SEH unwind diagnostic. Trace the failing compiler entry point and add a regression test if the project’s existing tests cover this path; done means the reproducer compiles without the ICE and the regression remains covered.
