[Gwyddion-devel] Strange crash on "show and extract volume data"

[Lennart F. <le...@di...>]

Hello,

The Volume data "show and extract" dialog crashes here with
"*** Error in `gwyddion': realloc(): invalid next size: 
0x0000000002ae0890 ***" if the extend in z-direction is smaller than x,y

e.g. creating a brick with following pygwy code and selecting "show and 
extract" fails:


b=Brick(100,100,10,1,1,1,True)
import numpy as np
d=np.ones((100,100,10))*np.arange(10)/100.
print d.shape
b.set_data(d)
gwy_app_data_browser_add_brick(b, None, None, True)

while the same code with

d=np.ones((100,100,10))+np.arange(10)/100.

succeeds

the only difference are the values of the array, once it increases from 
0 to 0.09 and the other time from 1 to 1.09.
No idea what is happening here.

But it does not seem to have to do with pygwy.

Best regards
Lennart
