- Subject: RFC: Disable asan tests under ulimit -v
asan doesn't work under ulimit -v, which I want to use on shared hosts
to avoid causing trouble with runaway processes. There doesn't seem
to be a way within expect to access getrlimit/setrlimit, so in this
patch I call out to the shell to test the current limit, and give up
if I get back a number (rather than "unlimited" or an error message).
Thoughts?

* gcc.dg/asan/asan.exp: Don't run tests if ulimit -v is set.
* g++.dg/asan/asan.exp: Likewise.
