ICE during bootstrap with --enable-checking

[Andreas Jaeger <aj at suse dot de>]

Bootstrapping the current gcc CVS version on i686, glibc 2.1.2, Linux
2.2.14 with:
../egcs/configure --prefix=/opt/aj-mips --disable-nls  \
--enable-checking=misc,tree,rtl,gc,gcac 

I get the following ICE:

Shall I send the preprossed source?  It should be easy to reproduce
this - otherwise tell me.
