Author Name: Nyall Dawson (@nyalldawson) Only part of this is fixed -- the project loads now. But zooming/panning around the map still causes a segfault. It's actually unrelated to the project. Adding the raster image alone to a new project also causes segfaults when zooming in and out. |
|
Author Name: Nyall Dawson (@nyalldawson) I'm still seeing it. If I add the bo5.tiff file to a new project in epsg:4326 then I don't see any crashes. Setting the project to epsg:3148 and panning/zooming quickly crashes qgis.

Author Name: Mathieu Pellerin - nIRV (Mathieu Pellerin - nIRV) I'm also able to reproduce crash. Steps:
It won't take 10 sec for QGIS to crash. |

Author Name: Nyall Dawson (@nyalldawson) With latest master (27c5b93) I'm getting an instant segfault when reprojecting the raster - no zooming or panning required. |

Author Name: Mathieu Pellerin - nIRV (Mathieu Pellerin - nIRV) Nyall, over here, I still have to zoom in and out a couple of times for it to segfault using windows osgeo4w build 6e90ba3. This issue is reproducible 100% of the times I've tried. Is this on Radim's radar or should we alert him over mailing list? |
|
Author Name: Nathan Woodrow (@NathanW2) Confirmed here to. I needed to zoom in and out really fast with the mouse wheel. |
|
Author Name: Larry Shaffer (Larry Shaffer) I got it to crash once, but not again. Zooming gets really slow when zooming in beyond 1:1, but returns to normal once zooming out past 1:1 again. Could not get it to crash when only loading the raster in a clean project. Crash report attached. Tested on Mac OS X 10.7.5

Author Name: Nyall Dawson (@nyalldawson) Larry - when you loaded the raster in a clean project did you set it to reproject? I'm only seeing the crash with reprojection enabled. |

Author Name: Radim Blazek (@blazek) Unfortunately I cannot reproduce it. Can you attach a small raster + project to reproduce it? What data type it is? Does the raster have no data value? Does it happen if map canvas is fully covered by raster, i.e. no need to use no data. |

Author Name: Mathieu Pellerin - nIRV (Mathieu Pellerin - nIRV) Radim, try with the project in this attached zip file. I can reproduce this crash 100% of time on my windows machine.

Author Name: Mathieu Pellerin - nIRV (Mathieu Pellerin - nIRV) The raster in the above attached project is a geotiff that was created by QGIS' heatmap feature. It's data type is: Float32 - Thirty two bit floating point The crash does seem to happen "more" when zoomed out map canvas show all of raster. |

Crashes here also, good. Thanks. |

Author Name: Radim Blazek (@blazek) Fixed in changeset "6983ec39b23ba8261f75b95aa5cd47eec5f5cb66".

Author Name: Radim Blazek (@blazek) It should be fixed, we were really 1 byte out of block. |
|
Author Name: Mathieu Pellerin - nIRV (Mathieu Pellerin - nIRV) Radim, that was fast :) thanks. I think that'll effectively deal with a bunch of raster related crashes I observed in last few weeks. Landsat 7 imagery with no data value for example kept crashing on me. |
