First guess maybe some stale .o files wandering around compiled with 
another version of gcc/or other options. Linking stuff from 2.96 with 
3.2.x ones is probably not a good idea. If I recall right there were 
some ABI changes between those versions. Note that 2.96 is a redhat hack 
and not an official gcc release (the first versions of it were horrible).

Second guess compiler bug. Upgrade gcc. the last 3.4.x ones are pretty 
reliable.
