Not sure what you mean exactly but store_field shouldn't have been invoked on a
PARALLEL so the problem is very likely up in the call chain.

Why is the DECL_MODE of the result DFmode while its DECL_RTL has BLKmode?
What's the mode of the record type?

--- Comment #11 from John David Anglin <danglin at gcc dot gnu.org> ---
This is probably a bug in pa_function_value. Nominally, we return
5 to 8 byte aggregate values in a BLKmode because of the odd right
justification of the object. However in this case, we have a DFmode
aggregate and treating it as BLKmode causes the ICE.
