I got one sample myself. It causes Perl process to exceed virtual memory
quota during evaluation of a regular expression in sub parse_received,
due to deep recursion. This is not an essential function,
so a quick workaround like inserting a:
return {};
right after entering this routine is a quick band aid.
I'll see what can be done better.

Very true. At least in this particular case it is 'just' an exhaustion
of a process limit, so it is not likely to be a security threat.
