What if there is more than one "gcc" in the compiler path?
Otherwise LGTM.

I've kept the detect_leaks=0 because as kcc mentioned lots of tests
have leaks. If you desperately want this cluttered stderr you can
remove the detect_leaks=0 part from final patch (or I can do it
myself).

Fixed. This now allows user to override default script's ASAN_OPTIONS.
@Evgeniy: you can just remove detect_leaks=0 if you desperately want
this stderr clutter in runner's output.

I meant to say

I do this in the next block (autodetection is different clang and gcc
are different).

As Kostya mentioned there are numerous leaks in benchmarks which make
analysis harder. I can remove it if necessary.

Snap, believe it or not but that's a typo. It should be ASAN_OPTIONS
and the weird expression optionally inserts : in front of added
options (so that user can provide his own ASAN_OPTIONS).

i disable lsan in my local copy of this script because there are leaks
in several benchmarks :)

You probably need the same for CLANGXX
Why are you disabling leak detection? It is on by default, which means
you are benchmarking not the same thing that users run.
At least make it an option.
I don't understand this LD_LIBRARY_PATH magic, what's its for?
