--- Comment #1 from Philip Hazel <ph10@???> ---
This was always somewhat dodgy code, and since it was released I have
discovered that all kinds of compiler variations can alter the answer that you
get. With hindsight, it should never have been released. PCRE1 (the 8.xx
series) is very much in "maintenance only" mode. PCRE2 (the 10.xx series) has
been out for nearly 3 years now, and its most recent release, 10.30, no longer
uses the stack for remembering backtracking points. It keeps its own data in
frames whose size is known (and available). The amount of heap used can be
explicitly limited.

As no change in PCRE1 is likely in this area, I am closing this as WONTFIX.
