 Hi,
 
 I got the same error message after quiting from a running program using
 gdb in Debian sarge. It was apparently caused by changing some methods
 to virtual (and adding a virtual destructor) in combination with a
 *partial* rebuild of the code. The segmentation fault (which, when
 analyzed with gdb, leaded to the BFD error) went away after a complete
 rebuild of the code, so the problem may have been caused by partially
 incorrect debug information in the executable. Just a guess.
 
 If anybody is interested, I could try to reproduce it (unfortunately, I
 overwrote the offending executable) and check what happens with a CVS
 HEAD snapshot of gdb. 
 
 Regards, Joris Mooij
