1.5	26-Jul-2020	christos	If Unwind_Backtrace is broken, ctx.n will still contain ~0, and we will return that which poor behavior for the user, so return 0 instead. We could document ~0 to be an error, but that would deviate from the Linux behavior which is not desirable. Noted by Poul-Henning Kamp
1.4	22-Jan-2020	mgorny	Fix using gcc's unwind.h
1.3	30-Jan-2019	mrg	make the backtrace()'s tracer() return _URC_FOREIGN_EXCEPTION_CAUGHT when the array is full. it won't be able to do any more work if so, and avoids infinite loops in unwinding as seen on arm64. XXX: lack of signal support here means that backtrace() is useless XXX: from a signal handler, such as attempting to display the stack XXX: when handling a SIGSEGV.
1.2	24-Mar-2014	joerg	branches: 1.2.26; _Unwind_GetLanguageSpecificData is supposed to return a _Unwind_Ptr. This makes a difference on M68K as it uses a different register for integer vs pointer values.
1.1	26-May-2012	christos	branches: 1.1.2; 1.1.4; Add a similar to linux backtrace_* and execinfo.h family of functions
