[gdal-dev] GDAL autotest (mrsid_1) crashing on Win64

[Kirk McKelvey]

Tamas,

I believe this was happening because of a known issue allocating DLL objects on the heap.  I have made the stream objects into member variables to work around this problem on the trunk (r22052).  Let me know if your tests continue to fail.

Kirk.

I did some investigations related to the Win64 problem, but I have no clues how to get further with this problem.
I've used Unified_DSDK_8.0_win64-vc9 and the MSVC 2008x64 compiler and even the following code is causing heap corruption when running the mrsid autotest:

LTIOFileStream *ltiofs = new LTIOFileStream();
if ( ltiofs )
        delete ltiofs;  // heap corruption here

HEAP[python.exe]: Invalid Address specified to RtlFreeHeap( 00000000025E0000, 0000000001E97610 )
Windows has triggered a breakpoint in python.exe.

This issue seems to be related to the changes r21974<http://trac.osgeo.org/gdal/changeset/21974>

Best regards,

Tamas

Strange, nothing happened to the driver code in that range.  I will bring up a 64-bit build and see if I can debug it.  Am I correct that your 32-bit builds are passing this test?

Even,

According to the buildlog at http://vbkto.dyndns.org/sdk/  r21980 was still OK, and r21988 was already wrong.

Best regards,

Tamas

Tamas,

Indeed there have been recent changes. You might want to drop a note about that
to Kirk in ticket http://trac.osgeo.org/gdal/ticket/4002 . After latest fixes
from Kirk and me, I no longer see problems under Linux however.

I don't know which version of the GeoDSDK you are using. But, at least under
Linux, there's an ABI incompatibility of GeoSDSK v7 with latest libgeotiff (due
to the addition of new fields in geo_normalize.h) that cause crashes. But the
libgeotiff change is a bit older than the MrSID driver one, so it would be
surprising that Kirk changes have an impact on that. Under Linux, using version
8 solves that issue. If you revert only the changes of the MrSID driver (to what
it was before r21974), what happens ?

Best regards,

Even
