[Bug middle-end/30453] [4.3 Regression] Segmentation fault: Error detected at ali.adb:2240:1

[pinskia at gcc dot gnu dot org]

------- Comment #2 from pinskia at gcc dot gnu dot org  2007-01-13 00:00 -------
This is most likely the same issue as:
http://gcc.gnu.org/ml/gcc-patches/2007-01/msg01075.html

Why it only happens with Ada on ia64/hppa is a different question.

This fault is no longer occurring on hppa*-*-*.  I think Jan addressed
this, so I'm closing.
