Has anyone see the same? (gcc 7.3.1)

What configure args did you use?

Did you use --enable-address-sanitizer-flags or just set -fsanitize-leak in CXXFLAGS?

I'm trying now with --enable-address-sanitizer-flags and the configure script executed all the way through.  Debian, GCC 7.3.0.

​"​

-O2 -fsanitize=leak

​"​

​I think "​

--enable-address-sanitizer-flags

​" ​

​ adds "​

-fsanitize=address -fno-omit-frame-pointer

​"

(and either option works for me).

I wanted to do with -fsanitize=leak. I tried -O2, -O0, and adding  -fno-omit-frame-pointer

​

; neither of those

made any difference.
