I'm getting this on Mandrake 8.1:

% ./python Lib/test/test_anydbm.py
UåSì

Segmentation fault

Running under gdb I get this for the Python stack:

(gdb) ppystack

and this is the beginning of the gdb stack trace:

ldd tells me this about the _bsddb shared object:

% ldd build/lib.linux-i686-2.4/_bsddb.so 
    libdb-3.3.so => /lib/libdb-3.3.so (0x40023000)
    libgcc_s.so.1 => /usr/local/lib/libgcc_s.so.1 (0x400b3000)
    libc.so.6 => /lib/libc.so.6 (0x400bb000)
    /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

and rpm suggests I've got Berkeley DB 3.3.11 installed. Is that recent enough for the bsddb package (suggesting a bug in setup.py) or is something else going on?
