            Bug ID: 82984
           Summary: Execuable compiled with ASAN crashes with very limited
                    information on Linux
           Product: gcc
           Version: 5.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: sanitizer
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

I have run into an issue on Linux (RedHat): I have some C++ project compiled
with ASAN, the executable crashes with almost nothing useful.

The followings are the only stuff collected in ASAN logs:

==33856==ERROR: AddressSanitizer: SEGV on unknown address 0x7ffacd125490 (pc
0x7ffad5d9fa50 bp 0x7ffacd1254d8 sp 0x7ffacb49f228 T7)


I also have other cases that only
"=================================================================" printed in
the ASAN log.

It is appreciated if someone could suggest me on how to proceed with the
debugging. 


Best regards,

Ralph
