Description Carlos O'Donell 2019-02-25 14:44:05 UTC

+++ This bug was initially created as a clone of Bug #1612448 +++

Description of problem:
glibc is using custom debuginfo generation but it does not run gdb-add-index like /usr/lib/rpm/find-debuginfo.sh does. Therefore glibc-debuginfo is missing .gdb_index.

Version-Release number of selected component (if applicable):
glibc-debuginfo-2.27-30.fc28.x86_64

How reproducible:
Always

Steps to Reproduce:
dnf debuginfo-install glibc
time gdb -batch /lib64/libc.so.6

Actual results:
real	0m0.204s

Expected results:
real	0m0.119s
One can get this result after:
  gdb-add-index /usr/lib/debug/lib64/libc-2.27.so.debug
  readelf -S $PWD/libc-2.27.so.debug|grep -w gdb_index
  [80] .gdb_index        PROGBITS         0000000000000000  00f6a777

Additional info:
It is sure not such a big deal but given glibc is loaded with any program it is a needless slowdown by 0.1s of any debugging.

DJ,

Could you please look into fixing this in Fedora Rawhide?

Comment 2 DJ Delorie 2019-03-02 06:50:24 UTC

Fixed.  find-debuginfo.sh used to always include the index, now you must pass -i
