This looks more like a target bug as this is being called from ia64's reorg.

------- Comment #2 from wilson at gcc dot gnu dot org 2005-10-15 17:03 -------
I haven't been able to reproduce this. I tried building a stage1 IA-64 ada
compiler on both x86_64 and IA-64, using both mainline and the 20050826
snapshot, and none of these 4 compilers triggered the bug.
I am fairly confident that my patch for PR 24232 fixed this though.
I will try to do an Ada bootstrap on my IA-64 machine, and I will assume this
is fixed if the bootstrap succeeds. I'm not sure if I can do an Ada bootstrap
though; it has been a while since I last tried. I will soon find out.
