Here's the first of the problems on the regression tests on Snow Leopard.  I 
believe this same error occurs in all the iso/run/pass/long*.mod tests.

In gm2.log:

Compiling by hand shows the error, too:

But, not surprisingly, there is no error when just generating assembly code:

----------

 -fiso -S -o /Volumes/Fantom_HFS+/gnu/gm2/obj/gcc/testsuite/long.s 
/Volumes/Fantom_HFS+/gnu/gm2/gcc-4.1.2/gcc/testsuite/gm2/iso/run/pass/long.mod
----------

The assembly file is attached.

No surprise:

----------
kuru:testsuite lambert$ as -arch i386 long.s
long.s:40:FATAL:Symbol L00000000001$pb already defined.

I have a hunch the code generator is doing just what it was told, but I don't 
know enough about the internals to know where to start looking.
