Bug#859062: Apache2 segfaults when using ProxySet in a ProxyMatch block

[Alain Knaff <alain@knaff.lu>]

Package: apache2
Version: 2.4.10-10+deb8u8

Hi,

The following config causes a segmentation fault:

<ProxyMatch ^(localhost|(www[123]?\.)?mysite\.org\.lu):(22|25|143|587)$>
  ProxySet connectiontimeout=86400 timeout=86400
  ...
</ProxyMatch>


==>
# systemctl status apache2.service -l
...
