Hello List,

I wonder, if there any special setup was necessary to make coredumps non-empty.

When my program crashes it leaves only the following:

Stack trace:
Frame     Function  Args

despite is was built and linked with -g (so should have all the debugging info
intact).  I did not modify any shell limits from their stock values, either.

$ ulimit -a
core file size          (blocks, -c) unlimited
data seg size           (kbytes, -d) unlimited
file size               (blocks, -f) unlimited
open files                      (-n) 256
pipe size            (512 bytes, -p) 8
stack size              (kbytes, -s) 2025
cpu time               (seconds, -t) unlimited
max user processes              (-u) 256
virtual memory          (kbytes, -v) unlimited

Any insight will be greatly appreciated.
