They work just as well on ARM/linux/glibc as on x86/glibc/linux. (Exception chaining isn't working on any architecture, IIRC). There's a problem with nothrow functions on ARM though: GDC currently marks nothrow functions with TREE_NOTHROW. However, if such a functions throws an Error (which is legal in D) the program crashes. The solution is not setting TREE_NOTHROW, see here: https://github.com/jpf91/GDC/commit/935198bda01ada89d946ee28819253cca872bea5 > > Does anybody know if there are any good articles of exceptions > and unwinding in gcc or in general? > > The keywords here are 'dwarf exceptions' and 'sjlj exceptions' (or setjump/longjump exceptions) and you probably want 'dwarf exceptions'. http://gcc.gnu.org/ml/gcc/2002-07/msg00391.html
