<div>Hi List,</div>
<div><br>
</div>
We use GDAL v3+ in our Open Source mapping application
MapWinGIS.
<div>We build using VS2019 on Windows and we use the files from
GisInternals.</div>
<div><br>
</div>
<div>We have a GeoProjection class which in turn calls
some/most OGRSpatialReference methods.</div>
<div>When calling OGRSpatialReference.importFromESRI() compiled
for Win32 we have no issues.</div>
<div>When calling the same code compiled for Win64 we get this
exception:</div>
<div>Exception thrown at 0x00007FFD93074839
(gdal304.dll) 0xC0000005: Access violation reading location
0xFFFFFFFFFFFFFFFF</div>
<div><br>
</div>
<div>We also implement the very similar method importFromWkt().
This method has no issues on Win32 or Win64.</div>
<div><br>
</div>
<div>Here's some relevant code from GeoProjection.cpp:</div>
<div>STDMETHODIMP CGeoProjection::ImportFromESRI(const BSTR
proj, VARIANT_BOOL* retVal)<br>
{<br>
AFX_MANAGE_STATE(AfxGetStaticModuleState())<br>
USES_CONVERSION;<br>
<br>
const CString s = OLE2A(proj);<br>
const OGRErr err =
ProjectionHelper::ImportFromEsri(_projection, s);<br>
<br>
*retVal = err == OGRERR_NONE ? VARIANT_TRUE : VARIANT_FALSE;<br>
if (err != OGRERR_NONE)<br>
{<br>
ReportOgrError(err);<br>
}<br>
return S_OK;<br>
}<br>
</div>
<div><br>
</div>
<div>STDMETHODIMP CGeoProjection::ImportFromWKT(const BSTR proj,
VARIANT_BOOL* retVal)<br>
{<br>
AFX_MANAGE_STATE(AfxGetStaticModuleState())<br>
USES_CONVERSION;<br>
<br>
const CString s = OLE2A(proj);<br>
const OGRErr err =
ProjectionHelper::ImportFromWkt(_projection, s);<br>
<br>
*retVal = err == OGRERR_NONE ? VARIANT_TRUE : VARIANT_FALSE;<br>
if (err != OGRERR_NONE)<br>
{<br>
ReportOgrError(err);<br>
}<br>
return S_OK;<br>
}<br>

<div dir="ltr">OGRErr
ProjectionHelper::ImportFromEsri(OGRSpatialReference*

char* s = proj.GetBuffer();<br>
return sr->importFromESRI(&s);<br>

return false;<br>
}<br>
<br>
char* s = proj.GetBuffer();<br>
return sr->importFromWkt(&s);<br>
}<br>
<br>
We're currently upgrading from GDAL2+ to
GDAL3+.</div>
<div dir="ltr">Users report the crash in both
versions.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">Most likely we're not calling
the <span>importFromESRI</span> correctly.</div>
<div>Please advice.</div>
