--- Comment #4 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
The difference is that darwin doesn't give symbols associated with the
backtrace (the "in main" part). This should be ultimately fixed in libbacktrace
(see for example: https://gcc.gnu.org/ml/gcc/2012-10/msg00053.html), because as
I understand it it is libbacktrace that provides symbolization for
libsanitizer.

In the meantime, the testsuite requirements should be relaxed. The question for
the sanitizer maintainers is: is Dominique's patch acceptable to achieve this?
