Hi all, I often get SIGBUS when my code (<a href="http://qgis.org" target="_blank">qgis.org</a>) hits stuff like this:<br>
<br>
GEOSCoordSeq_getX( cs, j, ( double * )&mGeometry[position] );<br>
<br>
if I change the call to use memcpy like<br>
<br>
double a;<br>
memcpy( a, &mGeometry[position])<br>
GEOSCoordSeq_getX( cs, j, &a )<br>
<br>
then all works correctly, the issue is that I've a lot of those calls and If I'm not wrong in the past it used to work). could this be because of a compiler setting? I'm using necessitas Qt sdk with ndk r8b1 compiling both with -mthumb and without has the same issue.<br>
<br>
thanks a lot<br>
Marco<br>
