Ah. The makefiles aren't adapted to disable optimization in editline.

(remove the -O and -O6)

$ make -C main/editline

That should get you an unoptimized editline.

>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>    Affects Versions: 1.8.23.0, 11.5.0
>         Environment: HP Proliant DL320e G8
> Debian Wheezy (kernel 3.2.0-4-amd64)
> DAHDI 2.7.0 (no cards installed)
> Libpri 1.4.14
>            Reporter: A. Iglesias
>
> New installation in this server. After everything is installed and asterisk started, anytime a try to open an asterisk console with asterisk -vvvvvvvvvr I get a "Segmentation fault" and console doesn't open, but asterisk keeps running. If I stop asterisk and try to start it with asterisk -vvvvvvc, it fails in the same way.
> I've been doing some research, and found a guy with the same problem in the past, related whit the value of the TERM system variable. In my case is "xterm", but if I change it for a non existent value ('lalalala' for example) then console starts.
> Digging deeper, I've found that the problem is in main/editline/term.c , in line 960 when executing this:
> term_alloc(el, t, tgetstr((char *)t->name, &area));
> If I change this line with the one executed when TERM has an unknown value...
> term_alloc(el, t, NULL);
> ... and recompile, then console starts.
>  the problem seems to be in the tgetstr function, because if I add a line just with this...
> tgetstr((char *)t->name, &area);
> ... I get the same error.
> I'll try to get core dump stuff, but maybe with this info is enough at the moment to find a solution. I've been trying to find the problem/solution studying the code, but no luck yet.
