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
