The call to write_RRA_row() is probably being optimized out. However, we
may be able to get the info we need now that the symbols are available.

(gdb) select 4
(gdb) p *rrd
(gdb) p rra_idx
(gdb) p rrd->rra_def[rrd_idx]
(gdb) p rrd->rra_def[rrd_idx].cf_nam
(gdb) p rrd->rra_def[rra_idx].pdp_cnt
(gdb) p ds_idx
(gdb) p rrd->ds_def[ds_idx].ds_nam
Also, I have a few other questions:
- is it always the same RRD file that causes the crash?
- does that RRD cause the crash every time?
- do you have any similar files (i.e. same RRA and DS definitions) that
do not cause crash?
