Then, generate a backtrace using: Then, generate a backtrace using:
--------- --------------
backtrace backtrace full

Also, getting an overview of the local variables might help:
-----------
info locals

If your backtrace looks like this:
---------------------------------------------------------------------------------------------------
(gdb) backtrace
#0 0x041b1a01 in vfprintf () from /lib/libc.so.6

their filename starts with src/ and has a line number. In this case, frame 2 would be the correct
frame, so before getting the local variables, switch to frame 2:
-----------
frame 2
info locals
