[Gdal-dev] GDAL hanging on TIFF operation?

Frank et al. -
I seem to have done something strange with my build config to cause this
problem. I have been building GDAL with external TIFF and GeoTIFF
libraries (mainly for rather old, historical reasons). Although I did
nice clean rebuilds of everything, and things looked fine, there was
clearly some inappropriate interaction or bad build karma going on (the
GeoTIFF code was hanging trying to allocate 0 bytes to read a line from
the epsg_csv file.
Since my "historical" reasons aren't really relevant any more, I
reconfigured GDAL to use the internal libtiff and geotiff libraries, and
the problem went away. I still need to investigate the problem so I
understand what went wrong, but this is clearly a user error.
Thanks for the help, Frank.
