            Bug ID: 69004
           Summary: -fprofile-use stage fails on ARM
           Product: gcc
           Version: 4.9.3
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tulipawn at gmail dot com
  Target Milestone: ---

Hi,

I'd managed to build the C program in question on x86 Linux using the same
compiler version (gcc 4.9.3) with the exact steps so I expected to repeat the
procedure on armv7 (Odroid C1, Ubuntu 14.04) as well, however I'm getting this
error:

`error: corrupted value profile: value profile counter` 

and so on during the profile-use stage. 

Steps used:

1. -O3 -fprofile-generate -ftest-coverage and -lgcov
2. run the program
3. -O3 -fprofile-use and -lgcov

If you're interested in looking into this, please advise on how to provide more
debug info.

Thanks
