     I want to refer to a figure in the caption of another figure. LaTeX
     runs fine on the first run, but crashes the second run. Is there any
     LaTeX specialist being able to tell me how to do it?
     
     Following is a sample code as well as the output of TeX:
     
     :
     :

     \caption{another example of figure \ref{example}}


As the LaTeX manual points out, `\ref' is a so-called `fragile'
command, that must be `protected' when used in text that is written to
one of the auxillary files .aux, .toc, etc.  So. you should have
written:

     \caption{another example of figure \protect\ref{example}}


The problem is, that the macro `\ref' is expanded to early. The
`\protect' ensures, that it is not expanded until the actual
typesetting is taking place.
