Description

Frank,

continuing on the special projection of the Province of Bolzano (Italy),
I have got a segmentation fault in gdal_translate (today's CVS).

I am using a LANDSAT-7 scene from GLCF

gdalwarp -order 2 -t_srs '+proj=tmerc +lat_0=0 +lon_0=9 \

So far so fine (coordinates are correct, false northing etc is applied
properly). Also the ellipsoid is applied now (thanks for the recent change).

Then I wanted to cut out a piece:

gdal_translate -of GTiff -projwin 610000 205000 767840 118240 \
      p192r028_7t20010826_z32_nn10_PBZ.tif \
      p192r028_7t20010826_z32_nn10_PBZ_small.tif
Input file size is 8765, 7797
Computed -srcwin 7 291 5538 3044 from projected window.
0.Segmentation fault

strace tells:
...
write(2, "Computed -srcwin "..., 57Computed -srcwin 7 291 5538 3044 from
projected window.
) = 57
write(1, "0.", 20.)                       = 2
open("p192r028_7t20010826_z32_nn10_PBZ_small.tif",
O_RDWR|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = 3
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

I have stored above file onto your FTP site, 
ftp://gdal.velocet.ca/pub/incoming/p192r028_7t20010826_z32_nn10_PBZ.tif.gz

Maybe you see a chance to look into this.

Thanks in advance,

 Markus

I'm not sure what was going on with this translation; however, 
I have confirmed that it seems to work now.  

Closing.
