Suddenly? Does it now cause problems on input that was o.k. before? That 
would be very strange...

I don't think that it has the power to do so, but more likely the kernel 
just dies, which looks like a bug.

Unfortunately without any code or examples it's hard to tell: for the 
usual toy examples FindCurvePath works alright so it would be necessary 
to at least have an example which makes it crash. If it really makes the 
Kernel crash, you also should send such an example to WRI so they can 
have a look at it and fix it (I think a silent kernel crash will always 
count as a bug :-).

hth,
