Subject Segmentation faults when SSLProxyCheckPeerName On
Date Tue, 18 Feb 2014 14:53:53 GMT
Hi,
since we've enabled SSLProxyCheckPeerName our reverserse proxy I can see
AH00052: child pid 5711 exit signal Segmentation fault (11)
in our logs during Nessus scans.

Backend server has several X509v3 Subject Alternative Names and Nessus sends 
just IP as Host header.

We are running: Apache/2.4.7 (Unix) OpenSSL/1.0.1f

Mod_backtrace says:
