Error producing a plot after updating to 0.91.1

Hi

Since updating to 0.91.1 one of my scripts, attached, has stopped
working. I get the following error when trying to run it

$ ./plot.py data.dat plot.png
alloc: invalid block: 0x1c15fa4: 40 1 0

Abort trap
$

Any ideas what could be causing this?

Cheers

Can you also please attach your data -- or point to some acceptable data online? What platform and backend are you using?

Cheers,
Mike

I've attached an example data file. I'm using the TKAgg backend on
Mac OS X Leopard.

Unfortunately, I'm not able to reproduce this bug on RHEL 4. Valgrind (a memory checking tool) doesn't come up with any clues.

You could try setting your backend to simply "Agg" to rule out some Tk usage/installation problem as the culprit.

Other than that, I'm stumped, but maybe one of the Leopard users on this list has more insight.

Cheers,

Thanks, the problem goes away if I use the Agg backend.
