[gdal-dev] GDALWarpOperation.ChunkAndWarpImage on source without CRS

[Radim Blazek]

Hi,
I am using GDALWarpOperation.ChunkAndWarpImage to read data,
everything works well except when a source dataset does not have a CRS
defined. Then it crashes with

#0  GDALGenImgProjTransform (pTransformArg=0x0, bDstToSrc=1, nPointCount=84,
    padfX=0xa1093f0, padfY=0xa109690, padfZ=0xa109930, panSuccess=0xa1090a0)
    at gdaltransformer.cpp:1402
#1  0x01f56c6c in GDALWarpOperation::ComputeSourceWindow (this=0xbf7fd214,
    nDstXOff=0, nDstYOff=0, nDstXSize=32, nDstYSize=32, pnSrcXOff=0xbf7fd12c,
    pnSrcYOff=0xbf7fd128, pnSrcXSize=0xbf7fd124, pnSrcYSize=0xbf7fd120)
    at gdalwarpoperation.cpp:1977

gdaltransformer.cpp:1402:

        pGCPTransformArg = psInfo->pDstGCPTransformArg;

but if I grep gdal for pDstGCPTransformArg it does not seem to be set at all.

Could you please give mi a hint? The code is here and above:
