[Crash-utility] bt -g not working since 5.1.9?

[Petr Tesarik]

Hi,

I noticed that the "-g" option to "bt" seems to have no effect in recent crash 
versions. And indeed, 5.1.8-to-5.1.9.patch contains the following chunk:

--- crash-5.1.8/kernel.c	2011-10-17 14:06:31.000000000 -0400
+++ crash-5.1.9/kernel.c	2011-09-28 15:31:00.000000000 -0400

-#else

 			bt->flags |= BT_USE_GDB;
+else
+			bt->flags |= BT_THREAD_GROUP;
 #endif
 			break;
 
Note that the hash sign is missing, so the pre-processor only leaves the 
"break" statement... The following patch seems to help.
