Description Andreas 2013-04-03 12:37:29 UTC 
As the summary says gdb segfaults when the gnome-terminal is resized and the "layout asm" feature is being used at the same time.

Use case in the gnome-terminal:
$ gdb
GNU gdb (Ubuntu/Linaro 7.3-0ubuntu2) 7.3-2011.08

(gdb) file ~/Desktop/test 
Reading symbols from /home/andreas/Desktop/test...done.
(gdb) layout asm
(gdb) 

Now do the following:
1. Resize the terminal window
2. Press <Enter>
3. Resize the terminal window
4. Press <Enter>

And bang segfault.

This also happens with the latest: GNU gdb (GDB) 7.6.50.20130403-cvs

Comment 2 Michael Fiedler 2015-09-15 11:04:23 UTC 
I can reproduce this using version 7.4.1-debian from Debian 7 wheezy x86:

[~]$ gdb -v
GNU gdb (GDB) 7.4.1-debian
...
This GDB was configured as "i486-linux-gnu".
...


I can NOT reproduce this using 7.7.1-0ubuntu5~14.04.2 from Ubuntu 14.04 x86_64:

$ gdb -v
GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1
...
This GDB was configured as "x86_64-linux-gnu".
...


I can NOT reproduce this using the most recent Git commit ade90bdeb78ccaeb294e34af04751f2f649a324f on Ubuntu 14.04 x86_64:

$ gdb -v
GNU gdb (GDB) 7.10.50.20150915-cvs

Thanks.  I'm closing this.  I believe this was addressed in 7.10; setting milestone accordingly.
