This may be an issue with GDAL itself, e.g. an external library having
been updated without rebuilding GDAL. If that's the case, any program
which calls GDALAllRegister() (e.g. "gdalinfo --formats") would
exhibit the same issue.

Alternatively, it may be an issue with GDAL and GRASS using different
versions of a common library (e.g. libstdc++). If you've updated any
system libraries, perform a full re-compile of GRASS (after "make
clean") and ensure that GRASS isn't built against a "private" version
of any system library used by GDAL.
