it is the PCRE regex to parse the email, it needs recursion. It may not use the
16MB but most of apache builds out there use a way too small stack size on
windows. Much smaller than on Linux.

16 Mo to manage a 160 length string...
I'm not enough good to understand :(

After
editbin /stack:16777216 httpd.exe
I get bool(false) while running under apache. Previously crash with the default
value. Seems like it can be solved with just increasing the stack size

Can you try in CLI please? While you did not provide a backtrace, I am pretty
sure
it is related to PCRE stack limit issue.
