Strange - Value can't be converted to integer.

["Gianni Mariani" <gianni at mariani dot ws>]

With this morning's snapshot on the 5.0.1 branch I am getting 
strange behaviour.  I compiled gdb using gcc 3.0 on Linux
system with binutils 2.11.2 and base RH7.1 glibc.
 
gdb v5 gives the message "virtual baseclass botch" in the same
place. 
 
The snippet below shows a debug session.  It seems I just can't
de-reference anything from this class.
 
Any ideas ?

308         m_errorReporter = w_er;

312         if ( ! m_parse_complete ) {

314             // The parsing comes in 3 parts -
315             // 1. HTTP response e.g."HTTP/1.0 200"
316             // 2. HTTP headers delimited by two new lines
