here sort of implies that.

Martin, are you expecting this build to have 64 bit or 128 bit long doubles?
The default should be 128 as it is natively but for some reason the cross

I compared what happens with long double and they are very different

If both compilers default to ibmlongdouble, both should use TFmode, no?

confgures are identical.
Default compiler options are also identical, from -Q --help=target:
The following options are target specific:

So what causes this TF vs. IF? Cross and native should be exactly the same,
but perhaps there is a difference in the configurations you have for the two?

Martin, can you please check whether you still see this ICE?

This doesn't fail for me using a native build. Martin, can you recheck to see
