rrdtool dumps core



Hi,

I'm using rrdtool-1.2.23nb1 on several NetBSD servers (i386 3.1.1 and amd64 4.0_RCx) and on all servers I see weird crashes (=core dump) when generating the "last 12 months" image if the time is 03:00 - 04:55.

During other times (05:00-24:00-02:55) I have no problems at all. Also I have no problems generating the "last 24 hours"/"last 7 days"/"last 4 weeks" images even if the time is between 03:00 and 04:55.

I'm living in Finland so my time zone is currently +3 hrs.

I put these in /etc/mk.conf

INSTALL_UNSTRIPPED=YES
CFLAGS+=       -g -static
CXXFLAGS+=     -g -static
LDFLAGS+=      -g -static

and these in pkgsrc/databases/rrdtool/Makefile

CONFIGURE_ARGS+=        --enable-debug
CFLAGS+=                -static

and built a debug version. However, I couldn't make any sense from the gdb...

Anyone else having this kind of problems with rrdtool?
