g++ dies on volatile structs

[Bill Currie]

NOTE: I'm not subscribed to this list, so please CC me any replies.

Using the code below (ice.cc), I get an internal compiler error.

This is from a freshly ported egcs (hppa1.1-stratus-sysv4), but
gcc-2.8.1 (hppa1.1-stratus-sysv4 and i860-stratus-sysv4 (I got gcc to
work on the bigendian i860)) also exhibits the same error.  I haven't
tried it on any other configuration yet (I havn't built a recent g++ at
home) but gcc-2.7.2.1 (hppa1.1-stratus-sysv4) does not produce this
error.

The stage3 and stage2 versions compared successfully (only LANGUAGES=c
done).  stage1 was built using gcc-2.7.2.1. 

If any other details are needed, just ask.

    x.x=1;
