Actually only the slight modification is needed to the linked patch.
If I change the second agrument to create_tmp_var/create_tmp_var_raw to "C" instead of NULL, we 
no longer get an ICE.

I don't understand why passing NULL to those functions change anything but oh well.

As mentioned the patch is the wrong approach. And also the C++ front-end have the same issue, see 
PR 23171.
