--- Comment #13 from jonne <gcc at zutt dot org> ---
Thanks for all your help, Martin, I really appreciate.
I re-ran with ASAN_OPTIONS as you suggested. The program seems to get killed
after about 44 seconds.
I already tried with clang before, seems to work ok over there. I'll attach
some output for clang below as well.
