Yes.
The only change that I see that could cause this is:

I will have a look at it next week (if it can be reproduced on the hppa in the
compile farm). Nevertheless, the interesting thing is that the patch only
makes SRA to do less, never more. Does the ICE happen even if you switch SRA
off completely with -fno-tree-sra ? Thanks.

A cross-compiler from your favorite linux box is sufficient.

Hum, yes, you're right, the ICE comes from PRE, not SRA.
