Sorry I didn't make myself clear. The reason I asked YOU to do it is because i tried it on my system and im not getting the backtrace (it's all question marks). Attach the core to gdb. At the gdb prompt, go to frame 2 by typing (gdb) f 2 There, for each of the variables i asked you to get the values of, type p followed by the variable name. For instance, to get the value of the variable 'odirect', do this: (gdb) p odirect and gdb will print its value for you in response. -Krutika On Mon, Aug 1, 2016 at 4:55 PM, Mahdi Adnan <mahdi.adnan at outlook.com> wrote:> Hi, > > How to get the results of the below variables ? i cant get the results > from gdb. > > > -- > > Respectfully > *Mahdi A.

Many thanks,
here's the results;
(gdb) p cur_block$15 = 4088(gdb) p last_block$16 = 4088(gdb) p
local->first_block$17 = 4087(gdb) p odirect$18 = _gf_false(gdb) p
fd->flags$19 = 2(gdb) p local->call_count$20 = 2
If you need more core dumps, i have several files i can upload.

Sorry I didn't make myself clear. The reason I asked YOU to do it is
because i tried it on my system and im not getting the backtrace (it's all
question marks).
Attach the core to gdb.
At the gdb prompt, go to frame 2 by typing
(gdb) f 2
There, for each of the variables i asked you to get the values of, type p
followed by the variable name.
For instance, to get the value of the variable 'odirect', do this:
(gdb) p odirect
and gdb will print its value for you in response.

Could you also print and share the values of the following variables from the
backtrace please:
i. cur_block
ii. last_block
iii. local->first_block
iv. odirect
v. fd->flags
vi. local->call_count
