I confirm that I can reproduce this on my 32-bit Linux box. The various
options don't seem to matter. However, increasing the workspace size
gives the PCRE_ERROR_DFA_WSSIZE and a different crash, so it's something
to do with the workspace. I'm afraid I have to go out now, but I will
try to track this down later today.

Thank you for all the PCRE testing that you do.
