Yeah, that comes from libgcc. The pointed question was aimed at whether you were
using the one from llvm's compiler_rt, which had a bug which has subsequently
been fixed, that manifested itself in a similar manner. But since you're not
using that, it's probably not the same problem.

When your processor hangs, can you tell if it's hitting an interrupt, and if so
which one?
