            Bug ID: 64234
           Summary: Statically sanitized executable does not export ASan
                    symbols
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: sanitizer
          Assignee: unassigned at gcc dot gnu.org

If executable is linked with -static-libasan, it won't export libasan public
API (__asan_reportXYZ, etc.), causing dlopens of sanitized shlibs to fail. Same
applies to other sanitizers (-static-libubsan, etc.).
