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.

Well, the workaround removes the ICE, but constructor handling
appears still broken:

ada/sem_prag.o(.text+0xa58): In function
`sem_prag.analyze_pragma.check_no_identifier':
../../gcc-head/gcc/ada/sem_prag.adb:1168: undefined reference to `C.1290.13979'

../../gcc-head/gcc/ada/sem_prag.adb:382: undefined reference to `C.3692.17381'
collect2: ld returned 1 exit status
make[2]: *** [gnat1] Error 1

(at least on s390 and s390x).
