core dump when 'making control.texi from control.txi' in 2.1.30 cvs sources

[Joao Cardoso]

Hi,


In the few last cvs versions of octave-2.1.30, munge-texi core dumps
when making control.texi. All other texi files are generated OK. The
control.texi.t tail:


* structaccess::                
* structintern::                
@end menu
