Ari,
fopr the crash in MEMRasterBand::IReadBlock(), I would suspect that
CPLScanPointer doesn't do its job rightly when compiled in MSYS environment.
The function looks currently like :
/* -------------------------------------------------------------------- */
/* On MSVC we have to scanf pointer values without the 0x */
/* prefix. */
/* -------------------------------------------------------------------- */
if( EQUALN(szTemp,"0x",2) )
{
pResult = NULL;
#if defined(WIN32) && defined(_MSC_VER)
sscanf( szTemp+2, "%p", &pResult );
#else
sscanf( szTemp, "%p", &pResult );
#endif
}
I'd guess we probably don't need the defined(_MSC_VER) test
I can confirm this. A simple copy to memory raster causes a segfault:
$tst = Geo::GDAL::Open('gdal-autotest/gdrivers/data/39079G6_truncated.dem');
$tst->GetDriver->Copy('MEM',$tst);
but when removing the above test, this code works fine. szTemp contains
prefix "0x" in MSYS.
A ticket and a bug fix is probably in order.
Regards,
Ari
