>
> While attempting to encode large messages, our team found that the PHP
> run-time would exceed its memory limit and die. Profiling and use of
> memory_get_usage showed us that we were spending a lot of time in append_str
> and that the PHP process grew after every call to this method, resulting in
> the leak-like behavior that caused the process to grow and then crash. We
> rewrote append_str to use the string concatenation operator instead of the
> somewhat elaborate scheme in place today (str_split, followed by the copying
> of one byte at a time from the latter array to the final string) and the
> memory usage issues disappeared with no loss of functionality. We would like
> to provide the patch to fix this issue.
