Vulnerability Development: Errors in IE - are they exploitable?

[Franklin DeMatto <franklin () qDefense com>]

Not to rarely, Internet Explorer crashes on me, with the Dr. Watson box 
popping up.  Now, I don't believe that these are simple buffer overflows 
and the like, but are rather more likely caused by a complicated internal 
state with some bugs in it.  They are certainly not easily 
reproducible.  My question is:  are these exploitable?  Using JavaScript, 
etc., it would easy to put IE through whatever loops are necessary to get 
to a particular state.
All I have to work with is the Dr. Watson logs & dumps.  Like I said, these 
are not easily reproducable.  If anyone has any advice on this, please 
share it.
