Bug#836864: libasan3: -fsanitize=address -static-libasan doesn't always work

[Vincent Lefevre <vincent@vinc17.net>]

Package: libasan3
Version: 6.2.0-3
Severity: normal

While -fsanitize=address -static-libasan works on a simple .c file,
it no longer works in a more complex case. To reproduce, build MPFR
(e.g. 3.1.4) with:

  ./configure CC=gcc-6 CFLAGS="-fsanitize=address -static-libasan"
  make
  make check

All the tests fail with the error:

  Your application is linked against incompatible ASan runtimes.

There's no reason why the ASan runtimes should be incompatible.
"gcc-6 -fsanitize=address -static-libasan" has been used everywhere!
