Hi there!
I have a fix for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61875.
This situation occurs when somebody decides to build GCC with
-fexeptions and -frtti which are forbidden for libsanitizer. They get
strange error (see bug above) which I know how to fix but think that I
should not. Instead of it attached patch forces configure to fail when
meet -fexceptions or -frtti option in CXXFLAGS.
--Marat
libsanitizer/ChangeLog:
2014-08-18 Marat Zakirov <m.zakirov@samsung.com>
* configure.ac: Check -fexceptions and -frtti.
* configure: Regenerate.
