<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>This seems to be linked with line 364 in
LoadValueNumbering.cpp, and my best guess is that the template struct
simplify_type in ilist isn’t being picked up for some reason, so classof
gets an ilist_iterator as an argument rather than the object the iterator
points to. It happens every time I try to dyn_cast<…>(I) where I is
an ilist_iterator, but in other cases I got around it by manually retrieving
the iterator’s value with dyn_cast<…>(&*I). On line 364
this technique doesn’t work.<o:p></o:p></span></font></p>
