[gdal-dev] ogrinfo PGeo segfault in libmdodbc.so mdb_free_indices()

[Dave Fuhry]

$ ogrinfo PGeo:Beaverhead

segfaults.  Is this definitely an mdbtools bug?  Here's the backtrace:

Program received signal SIGSEGV, Segmentation fault.

I'm using gdal from svn HEAD, mdbtools 0.6pre1, and unixodbc 2.2.11-16
(debian).  The file is the (large, sorry) mdb contained in
ftp://ftp.gis.mt.gov/CadastralFramework/Beaverhead/Beaverhead.zip

I'm having some trouble getting this working with a debug build of
libmdbodbc.so, but I'll send a backtrace with that when I can.
