             Bug #: 56628
           Summary: "bootstrap-lto  bootstrap-asan" / profiledbootstrap
                    fails
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: sanitizer
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: markus@trippelsdorf.de

During stagefeedback:
...
/usr/x86_64-pc-linux-gnu/bin/ld: error:
/var/tmp/gcc_build_dir/./prev-gcc/liblto_plugin.so: could not load plugin
library: /var/tmp/gcc_build_dir/./prev-gcc/liblto_plugin.so:
 undefined symbol: __asan_report_load8

Also the size in physical pages of the instrumented gcc during the build
is insane:
