+Subject: [patch] .gdb_index: Do not crash on NOBITS
+
+Hi,
+
+elfutils-0.148 still do not contain patch of its GIT
+804e9ca4d644e64a6125307cbf0a0b89477d7611 where the .gdb_index section has been
+also split into the separate debug info file.
+
+Due to it binaries split using elfutils-0.148 contain
+  [38] .gdb_index        NOBITS           0000000000000000  0000338c
+instead of expected
+  [28] .gdb_index        PROGBITS         0000000000000000  0000211c
+
+and due to it GDB while reading the file can error() by:
+Reading symbols from x.debug...Dwarf Error: Can't read DWARF data from 'x.debug'
+
+which should not be fatal but due to some other bugs therein it can crash GDB.
+
+The wrong separate debug info file is for example:
+http://kojipkgs.fedoraproject.org/packages/glibc/2.12.90/10/x86_64/glibc-debuginfo-2.12.90-10.x86_64.rpm
+/usr/lib/debug/lib64/libutil-2.12.90.so.debug
+
+OK to check-in?
+
+It does not attempt to use .gdb_index from the main binary, it will just
+disable .gdb_index usage on these binaries.
+
+
+Thanks,
+Jan
