For all those who have not yet read pcrestack(3):
As a very rough rule of thumb, you should reckon on about 500 bytes per
recursion. Thus, if you want to limit your stack usage to
8Mb, you should set the limit at 16000 recursions. A 64Mb stack, on the
other hand, can support around 128000 recursions.
pcre_match_limit_recursion 10000 (default)
thread_pool_stack 48k [bytes] (default)
So these obviously do not fit at all.
We we opt for keeping pcre on the stack, we should consider to auto-tune either
to sensible values.
