Comment 1 Francis Herne 2020-11-04 15:21:36 UTC 
Thank you for the report.

This was noticed already and fixed by Milian Wolff; the fix will be in 5.6.1 which should be released soon.

Comment 6 MadMartian 2021-07-18 21:06:10 UTC 
I'm still seeing this in KDevelop 5.6.1
Comment 7 Julian Wolff 2023-04-18 12:38:23 UTC 
I can reproduce this with gdb 13.1, KDevelop 5.10.221203

My .gdbinit ends with a few 'skip' lines:

skip -gfi /usr/include/c++/*/*/*
skip -gfi /usr/include/c++/*/*
skip -gfi /usr/include/c++/*

KDevelop seems to to be trying to interpret the output of those lines ("File(s) /usr/include/c++/*/*/* will be skipped when stepping.") as the version number.

gdb: skip to GDB version string

This change allows to use ~/.gdbinit file with constructions like
`skip -gfi /usr/include/c++/*`.
Problem with current implementation is that when .gdbinit contains such
strings GDB output produced is following:
```
File(s) /usr/include/c++/* will be skipped when stepping.
GNU gdb (Ubuntu 8.2.91.20190405-0ubuntu3) 8.2.91.20190405-git
```
And current implementation expects version on the first output from GDB.

This change fixes it by adding skip functionality during GDB session
initialization.
