Package: rrdtool
Version: 1.4.7-2
Severity: minor
Dear Maintainer,
I attach a python script to quickly setup the rrd archieve in current directory
(requires python-rrdtool). To get a segfault just run the script with
"python crash_rrd.py"
and then
"rrdtool fetch test.rrd AVERAGE".
The problem is in type of RRA I use in line 14:
'RRA:AVERAGE:0.5:1:36500'
It means that last entry will be somewhere in 100 years.
If I use something that fits in unixtime (not 100 * 265, but 20 * 365),
everything works fine.
The script and gdb output attached.

Do you need "set solib-search-path" or "set sysroot"?
