Description
Tested on both linux and windows xp with the following point vector
http://mapserver.uevora.pt/~mapserver/dados.rar
I mistakenly choose this point layer to create a TIN (points extracted from a altimetry line vector, so not really suited for the analysis), but I believe that a error message should be thrown instead of the crash. Nevertheless close the ticket if you consider this situation too extreme.

I have problems accessing the sample file (server connection times out).

Hi,
sorry for the broken link. I tested the tool again with what I believe is a vector identical to the one linked and it works fine now. So I'll close this then I'll test the linked vector and leave further feedback if necessary.

The link is working again, and running the interpolation plugin against this vector crashes qgis.

ok, I have the testdata now and can reproduce the bug.

Data are no longer available. Any hope of having this fixed?

#7 Updated by Giovanni Manghi about 14 years ago
I can provide the data again. Marco has it in any case. The crash was confirmed but I don't know if anything has been done yet.
#8 Updated by Anne Ghisla over 13 years ago
I wish to replicate the bug, are the data available somewhere else? Can you share them, Marco?
#9 Updated by Alister Hood over 13 years ago
Here is a link for a (very large) contour shapefile which crashes my QGIS as soon as starting TIN interpolation. N.B. the interpolation plugin is not really suitable for large files (polyline files - I'm not sure about point files) anyway - it takes many hours to do an IDW interpolation, even at a low resolution.

"And here is a backtrace, it looks like there is a loop, I snipped a lot: http://paste.ubuntu.com/780464/ "

Confirmed for http://dl.dropbox.com/u/24564149/0.1m_Contour_combined.zip which is very big data ..
but not for http://sengis.uni-hohenheim.de/tmp/interpolation_bug_tin.zip
neither on release-1_7 branch nor master branch ..
So it seems the problem only exists with very big data ..
Setting Priority normal as it seems not to be a showstopper for "normal" cases ..
Still the plugin seems not to handle big data very well

- File test2.xyz added
Same problem: Segmentation fault using the "interpolation" plugin and the TIN method on a xyz dataset (Z interpolation).
I checked the patch attached in #5239 but it did not fix the problem.
According to my tests, qgis crashes when the points to interpolate are too close (too dense dataset).
I enclose a dataset that causing qgis to crash. Use the SCR ID 10090.
Please can you test this dataset and report if it crashes or not?
Thanks!
