>Description:
Sometime between 4/26 and 4/29, compile/20011119-2.c regressed.  It worked here:

http://gcc.gnu.org/ml/gcc-testresults/2002-04/msg01050.html
http://gcc.gnu.org/ml/gcc-testresults/2002-04/msg01168.html

It fails here:

http://gcc.gnu.org/ml/gcc-testresults/2002-04/msg01165.html
http://gcc.gnu.org/ml/gcc-testresults/2002-04/msg01120.html

When I compile it by hand using today's checkout, I get:

compile/20011119-2.c:1: warning: weak declaration of `foo' after first use results in unspecified behavior
/usr/ccs/bin/as: "/var/tmp//ccrCbkea.s", line 51: error: invalid operand

I've attached the .s output.
