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

[Tamas Szekeres]

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
