Description Karel Klíč 2011-08-08 11:20:01 EDT
Several problems related to debuginfo were found in the uuid-1.6.1-10.el6 package. These issues might affect crash analysis done by Automatic Bug Reporting Tool and its retrace server, and also prevent proper debugging of crashes via GDB.

Debuginfo missing for binaries
------------------------------
A debuginfo file for a binary is not present in the debuginfo package. This might be caused by:
 - binary being compiled without debugging information
 - debugging information being removed from the binary by a build script
 - rpmbuild failing to extract debugging information from a binary in a buildroot because of permissions (eg. suid binaries, binaries without executable flag set)

affected binary: /usr/bin/uuid
affected package: uuid-1.6.1-10.el6.i686
binary doesn't contain debug sections (it was probably stripped)
affected binary file mode: 100755

This issue can be investigated by using eu-readelf tool from the elfutils package. Use `eu-readelf --notes /path/to/binary` to get build ID of a binary. Then check that the debuginfo package does not contain /usr/lib/debug/.build-id/<aa>/<bbbbbbbb>, where <aa> are the first two chars of the build ID, and <bbbbbbbb> is the rest of it. It should be a symlink pointing back to the binary.

No .debug_info section in a debug file
--------------------------------------
When a binary is compiled without gcc's -g option, no debugging information is generated and rpmbuild creates almost-empty debuginfo file, which cannot be used for debugging. Please fix the package build process to use $RPM_OPT_FLAGS, which include the -g option among others.

- path: /usr/lib/debug/usr/lib/libossp-uuid.so.16.0.21.debug
  package: uuid-debuginfo-1.6.1-10.el6.i686
- path: /usr/lib/debug/usr/lib/libossp-uuid++.so.16.0.21.debug
  package: uuid-debuginfo-1.6.1-10.el6.i686
- path: /usr/lib/debug/usr/lib/libossp-uuid_dce.so.16.0.21.debug
  package: uuid-debuginfo-1.6.1-10.el6.i686

This issue can be investigated and tested by using eu-readelf tool from the elfutils package. Use `eu-readelf --section-headers /usr/lib/debug/usr/bin/<debuginfofile>.debug` to see if debuginfo file contains .debug_info section. It is supposed to be there.

(This bug was detected and filed by a script.)

reproducible, there is install -s in Makefile
