[Visualpython-users] segfault with visual 5.11 / python 2.5.4 / Debian i386
|
From: Sanjoy M. <sa...@MI...> - 2009-08-12 19:31:50
|
On Debian GNU/Linux (i386, 'unstable' distribution), I get a segfault
with the following vpython script. I'm using v5.11 as packaged in
Debian, with Python 2.5.4 from Debian.
Does anyone see the same problem?
I eventually figured out one problem with the script: the "F -=
ball.m*g" line needs a vector on the right-hand side. But I don't think
it should segfault even with that mistake.
By the way, valgrind is not very happy with the script, and also gives
something of a backtrace for the segfault. I've included the end of the
output of "valgrind --leak-check=full python /tmp/script.py"

from visual import *
cd = 0.5 # drag coefficient for a sphere
ball = sphere(pos=(0,0,0), # in m
color=color.red,
radius=0.05) # in m
ball.v = vector(10,0,10) # in m/s
ball.m = 0.5
g = 10
endpoint = sphere(pos=(20,0,0))
startpoint = sphere(pos=(0,0,0))
scene.autoscale = 0
trail = curve()
dt = 0.0001
area = pi * ball.radius**2 # cross-sectional area of ball
while 1:
rate(int(1/dt))
ball.pos += ball.v*dt # use updated velocity to update position
trail.append(pos=ball.pos)
F = -0.5 * cd * area * ball.v * ball.v.mag
F -= ball.m*g
ball.v += F/ball.m*dt # force changes the velocity
And here is the valgrind output:
