Description (last modified by warmerdam)

GRIB driver asserts (crashes) on opening this dataset. The "nSectSize" is a large number, and the memory allocation fails. 

        memcpy( &nSectSize, abyHead, 4 );
        CPL_MSBPTR32( &nSectSize );

        if( VSIFSeekL( poDS->fp, nSectSize-5, SEEK_CUR ) != 0
            || VSIFReadL( abyHead, 5, 1, poDS->fp ) != 1 )
            break;

Status: new → assigned

The file works fine on my 64bit workstation but does fail with an error in CPLMalloc() allocated 1.9GB on a 32bit windows build.

Digging further.
