Thanks for your bug report. Here is a simple testcase.

# uname -a
Linux ocean.lucon.org 2.1.131 #101 SMP Sat Dec 12 08:26:21 PST 1998 i686 unknown
# gcc -S foo.cc 
/home/work/misc/gnu/src/egcs-1.1.1/gcc/function.c:3272: Internal compiler error in function instantiate_virtual_regs_1

BTW, egcs 1.0.3 is ok.
