I'd be interested to know if there is a case statement involved they 
take a long time to inline.   Have you walked away and came back and to 
see how long it takes.  If you have full optimization on, a level 8 
inlining and always inlining on it could take quite a while if there was 
a case statement.

If you could send a bit of code that shows this we could tell more.  
Perhaps the compiler is falling into some loop somehow.

I'd also be curious to how long it takes if you add this 
#pragma inline_bottom_up off

with the always_inline
