FYI, I managed to compile a C++ file containing only the function at line 206
without being able to reproduce the ICE.

Building with -O2 instead of -Os makes the issue disappear.

Finally, I could workaround the ICE by creating a dedicated function for the
computation of the "notches" variable, in case that helps.
