[MiKTeX] TeX capacity exceeded?

[Liu Y. T. <tho...@gm...>]

Hello, everyone!

I'm using beamer package to create slides. I added three pictures, each as a
frame. And I create another frame, the output gave those:

! TeX capacity exceeded, sorry [input stack size=5000].
\end #1->\csname end#1
                      \endcsname \@checkend {#1}\expandafter \endgroup
\if@e...
l.93 \end{frame}

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.


Here is how much of TeX's memory you used:
 12322 strings out of 95419
 209890 string characters out of 1187294
 270534 words of memory out of 1270650
 14911 multiletter control sequences out of 60000
 5758 words of font info for 21 fonts, out of 1000000 for 2000
 14 hyphenation exceptions out of 8191
 5000i,14n,4995p,423b,536s stack positions out of
5000i,500n,10000p,200000b,32768s
PDF statistics:
 350 PDF objects out of 300000
 27 named destinations out of 300000
 52 words of extra memory for PDF output out of 10000
!  ==> Fatal error occurred, the output PDF file is not finished!

I don't think the memory should overflow this easy, could anyone give me a
hint about it? Thanks!
