Title:
segfault in enblend/vigra
Status in Enblend:
Incomplete
Bug description:
Recently I discovered a segfault in enblend. It is a fairly big
project, so i can not *simply* provide input images (7.4 GB) or the
whole core dump (4.8 GB), but here's a stacktrace:

enblend version is
enblend 4.1-cd12da20db1a
The crash occurs in the very beginning of the stitching process:
enblend --compression=DEFLATE -l 29 -f181172x30821+8973+7238 -o
gigapixeltest.tif gigapixeltest0000.tif [...] gigapixeltest0066.tif
enblend: info: loading next image: gigapixeltest0000.tif 1/1
make: *** [gigapixeltest.tif] Segmentation fault
If necessary, I can also upload the files somewhere. Let me know what
I can do.
