libdvbpsi | branch: master | Jean-Paul Saman <[email protected]> | Tue Apr 15 13:04:29 2014 +0200| [87ed77d832763c0e14800172e67cc19f658b6abb] | committer: Jean-Paul Saman

configure.ac: Add option to use gcc version 4.8.x Adress Sanitizer (gcc-asan)

Beware using the AdressSanitizer from GCC 4.8 uses a lot of memory. You need
more then 8GB of memory in your machine.
