[rrd-users] Core dump on large step sizes

[Mike Schilli]

I'm getting a core dump with rrdtool 1.2.19 when graphing data with
large step sizes (1 year). Here's the commands to reproduce it:

    rrdtool create myrrdfile.rrd --step 31536000 \
     DS:money:GAUGE:63072000:U:U \
     RRA:MAX:0.5:1:5000

    rrdtool update myrrdfile.rrd 1311653013:100000

    rrdtool graph mygraph.png --end 1369419413 --start 1211653003 \
    DEF:draw1=myrrdfile.rrd:money:MAX "AREA:draw1#0000FF:Example"

Stacktrace:

Is this something that has been fixed in later versions?
