The problem occurs when OGR is used in a threaded environment (such as the MapGuide Server). In mitab_datfile.cpp the functions ReadCharField and ReadDateField both use a static allocated buffer to return the results. This causes memory violations when one thread is reading the buffer and another is writing it. The fix is simple, just add a member variable that can act as buffer, and remove the statically allocated buffers. This gives a slight overhead in memory consumption, but enables threading. The attached DIFF file can be used to patch the gdal/ogr version found in the MapGudie Server svn trunk (don't now the exact version used there)." defect closed normal 1.4.3 OGR_SF 1.4.2 normal fixed mitab threading Daniel Morissette
