[exim] Command killed by signal 139 in ACL

Hello everybody,

I've recently updated my FreeBSD to the latest STABLE (both kernel and
libs/tools), and after a reboot with the new kernel one of my Exim ACL's
stopped working.

Log contains records like this:
2005-12-15 04:02:28 H=HOST [IP] temporarily rejected connection in
"connect" ACL: failed to expand ACL string "${run{/etc/spam_test
$sender_host_address} {yes}{no}}": command killed by signal 139

Where /etc/spam_test is a simple program written in C. As far as I know,
this program isn't even being executed by Exim.

Signal number 139 may refer to 128 + 11 (SIGSEGV).

Have any of you ever heard of something similar?

Cheers,
