Example of leak sanitizer shows no debug information (so did applying sanitizer in my own project)

[brunoczim]

What I ran and what I got:

@bruno:lsan% RUSTFLAGS='-Z sanitizer=leak' cargo run --example rc-cycle --target x86_64-unknown-linux-gnu
   Compiling lsan v0.1.0 (file:///home/bruno/prog/rust/rust-san/lsan)

This solved my issue: https://stackoverflow.com/questions/24566416/how-do-i-get-line-numbers-in-the-debug-output-with-clangs-fsanitize-address

I think it is worth putting it on readme.

Sorry to continue posting here, but which answer exactly solved your issue?

I tried putting ASAN_SYMBOLIZER_PATH=/usr/local/bin/llvm-symbolize-6.0 in front of the whole sanitizer command, but it didn't help.
