            Bug ID: 97193
           Summary: .gcno files are not written to same directory as the
                    object file
           Product: gcc
           Version: 9.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mario at klebsch dot de
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

According to https://gcc.gnu.org/onlinedocs/gcc/Gcov-Data-Files.html, the .gcno
files should be written to the same directory as the object files.

> The .gcno files are placed in the same directory as the object file.

This seems to work with gcc 8.3.0 but does not work with gcc 9.3.0:
