Hi,
|
|
|
99f0af |
|
|
|
99f0af |
in Fedora 24 it still worked, in Fedora 25 it does not - *-debuginfo.rpm
|
|
|
99f0af |
no longer have the .gdb_index accelerating section now.
|
|
|
99f0af |
|
|
|
99f0af |
It happens because:
|
|
|
99f0af |
objcopy: unable to copy file 'foo.debug'; reason: Permission denied
|
|
|
99f0af |
|
|
|
99f0af |
*.debug files in Fedora were always 444 but the time gdb-add-index is run is
|
|
|
99f0af |
still before the *.debug split and in Fedora 24 the files were -rwxr-xr-x
|
|
|
99f0af |
that time while in Fedora 25 they are apparently no longer w.
|
|
|
99f0af |
|
|
|
99f0af |
OK for check-in?
