> Dear Fortranners,

> frontend optimization tries to inline matmul, but then it also needs
> to take care of the assignment to the result array.  If that one is
> not of canonical type, we currently get an ICE.  The straightforward
> solution is to simply punt in those cases and avoid inlining.

> Regtested on x86_64-pc-linux-gnu.

> OK for mainline?  Backport to affected branches?
