Comment #10 on issue 3359 by address@hidden: ties for notes in  
\changed Staff brings LP to crash
http://code.google.com/p/lilypond/issues/detail?id=3359

The patch for issue 542 skipped over a null pointer, but this problem does  
not involve null pointers.

After the patch for issue 3199, the Tie is on the list  
of 'pure-relevant-grobs' for the Staff that is not its parent.  This causes  
the 'pure-Y-common' for the Staff to be the overall VerticalAlignment (the  
common (grand)parent of Tie and Staff).  Then the initial page-layout asks  
the Staff for its 'pure-height', the Staff tries to answer in terms of its  
position relative to the whole system, requiring page-layout, and we have  
an endless recursion until the stack crashes.

Either the Tie is not 'pure-relvant' to the Staff, or 'pure-Y-common'  
should refrain from pointing to objects outside its own Staff (more  
generally VerticalAxisGroup) ... or maybe we define a pure-translation as  
an initial guess for a Staff position in the system, and  
then 'pure-pure-height' to estimate positions without triggering  
calculations of 'pure-translation' ...

Note that released builds give .pdf output showing the rest of the score  
with just the Tie misplaced, and debug builds give a reasonably-helpful  
message.
