<p class=MsoPlainText>Good day!<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I am experiencing a memory leak from looped calls to
GDALRasterIO(). It may be something I am doing improperly <br>
because I use/call RasterIO() in a C++ program that runs leak free.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I "migrated" the C++ code to the GDAL C API so
that I can integrate some really old C code downstream from the GDALRasterIO()
call.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>The leak was observed on v1.5.2, so I upgraded to 1.7.2
and am experiencing the same effect. <o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Are there special options or considerations when
compiling C code against the GDAL library?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Any suggestions?<o:p></o:p></p>
