Here is the original command:

I just tried on a FreeBSD 7.2 64 ; and it worked

On Ubuntu:
ERROR: malloc im->gdes[gdi].data

This is the simpliest form I found to generate the error:
/usr/local/bin/rrdtool graph /tmp/powerOPG2aY -l 0 \
-t 'SOLAR YEARLY (monthly average)' \
-x WEEK:1:MONTH:1:MONTH:1:18748800:'%b'  --slope-mode \

AREA:cext2#FFd700a0 \
CDEF:cext=cext0,cext1,+,cext2,+

changing the last line from CDEF:cext=cext0,cext1,+,cext2,+ to
CDEF:cext=cext0,cext1,+ ; then no error.

If I remove the start=xxxx:end=xxxx in each CDEF ; then the error doesn't occur.

I may try stepping into the code if the wife permits... No coding on
week-ends is the rule here !
