Package: octave
Version: 3.6.2-5
Severity: normal
Dear Maintainer,
I'm testing wheezy on a new machine.
I get a segmentation fault from __contourc__ when using the function contour() on a certain array.
More precisely, the seg fault occur inside contourc.m at the line:
## Now call __contourc__ for the real work...
c = __contourc__ (ii, jj, z, vv);
The seg fault will occur or not occur depending on the contour levels (vv) that are requested.
The same command applied to the same array works fine in squeeze, no matter what the contour levels are.
This array is of size 469x760, it does not contain any NaNs, and its min/max values are 30/4336.
The array is relatively complex (it is the topography of the ocean floor in a certain part of Antarctica).
I'd be happy to send a copy of the array to anybody who wants to give it a try.
Unfortunately I could not reproduce the bug with a simpler array (say, peaks()).
I am aware that such bugreport is of limited use, but please let me know if you have any suggestion on how to circumvent this seg fault.
Thanks,
Pierre
