>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Core/BuildSystem
>    Affects Versions: 13.4.0
>         Environment: Fedora 22, x86_64; but any distro with a compiler with sanitizers will do (excpet maybe Clang, since it reject's the use of trampolines that Asterisk uses).
>            Reporter: Jeffrey Walton
>
> GCC added sanitizers at 4.8. I'm attempting to build Asterisk with the sanitizers enabled (and then run the self tests).

> localhost asterisk-13.4.0]$ export CXXFLAGS=-fsanitize=undefined
> localhost asterisk-13.4.0]$ ./configure

> Looking at the config.log, it appears the CFLAGS and CXXFLAGS were tested and accepted. Then:
