[rrd-developers] Re: rrdtool bug?

[Tobias Oetiker]

Friday you sent me mail regarding rrdtool bug?:

*> This is under:
*> FreeBSD superfast.vger.com 3.3-RELEASE FreeBSD 3.3-RELEASE #0: Thu Sep 16 
*> 23:40:35 GMT 1999     jkh at highwing.cdrom.com:/usr/src/sys/compile/GENERIC 
*> i386
*> 
*> I'm getting the following errors from rrdcgi:
*> rrdcgi in free(): warning: junk pointer, too high to make sense.
*> rrdcgi in free(): warning: junk pointer, too high to make sense.
*> rrdcgi in free(): warning: chunk is already free.
*> rrdcgi in free(): warning: chunk is already free.
*> rrdcgi in free(): warning: chunk is already free.
*> rrdcgi in free(): warning: chunk is already free.
*> rrdcgi in free(): warning: chunk is already free.
*> rrdcgi in free(): warning: chunk is already free.
*> rrdcgi in malloc(): warning: chunk is already free.

it would be usefull if you could run this under gdb control and see
which instances of free generate these warnings ... the problem is
that I work under the asumption that freeing a pointer which
alreday points to NULL is of no harm ... but I could put a test in
for this to prevent free from being called ...

any thoughs on this folks ?

cheers
