Since PCH is somewhat desirable in general, and for Boost.Math in particular,
I don't think that disabling it altogether is right. Maybe, you can 
create a ticket with specific description of problems?

Also, did you report "compiler would segfault" to the appropriate persons?
That the first action here, I think.
