> Great care was earlier taken to not depend on execinfo.h's backtrace() which is non-portable. It was used if available, but it was not required. But now an unconditional core code dependency to it was added.
> This is also non-reliable on certain hardware architectures if the binary is fully stripped as there is no unwind information present. 
> Basically the function is used for purposes it should never be used for. Please replace the recursive call logic with something better. See attached patch for one suggestions.
