[Bug target/29472] New: [4.0/4.1/4.2 Regression] in reload, at reload1.c:1081 on m68k with -O2 -fPIC

[tbm at cyrius dot com]

I get the following ICE on m68k with -O2 -fPIC.  It fails with gcc 4.0, 4.1 and
4.2, and works with 3.3/3.4.

Martin, is this a bug you can still reproduce with the current SVN trunk?  If
so, could you provide a backtrace from gdb?
