I get a repeatable bus error when trying to plot more than

one histogram of simulated data. The first plot is generated

without error, but invariably a second plot crashes:

In [4]: x = random.negative_binomial(2, 0.25, 1000)

In [5]: from pylab import *

In [6]: hist(x)

Out[6]:

(array([240, 318, 206, 102, 65, 38, 17, 5, 6, 3]),

array([ 0., 3., 6., 9., 12., 15., 18., 21., 24., 27.]),

<a list of 10 Patch objects>)

In [7]: show()

In [8]: x = random.negative_binomial(2, 0.5, 1000)

In [9]: hist(x)

Bus error

This is using recent svn builds of numpy and maplotlib.

Hi Chris,

This just came up I think a day or so ago. Are you using TkAgg as your backend, and are you closing the plot window in between the two histograms?

Try updating from svn, Andrew just fixed a bug.
