Typically, Linux distributions build a modified version of GDB, with a number of addition patches. So, while I'm open to the idea of creating another corrective release in general, I'm not certain we have a sufficiently strong reason in this case. If there is a stronger push, perhaps... In the meantime, if you'd like, you can certainly ask on the gdb-patches mailing-list for permission to backport this patch to the gdb-10-branch. If given, before you can backport it, you'll need to create a GDB PR in bugzilla (https://sourceware.org/bugzilla/) so as to document this issue, and then ammend the commit message to include that PR number, e.g. like this commit: | gdb/ChangeLog: | | PR gdb/27614 | * contrib/gdb-add-index.sh: Fix when called with a symlink as an | argument. We'll also need to ask someone to create a 10.3 milestone and set the Target Milestone field to that new milestone. The PR is there to help us track precisely what changes went in the various corrective releases, and doing the above is part of our procedures for backporting changes to those corrective releases. -- Joel
