I run i386 builds with pcc fairly regularly (partial builds anyway, I have
a script that runs through most of what I know can be compiled) and have
seen no problems like that lately, what arch are you using and how do you
invoke pcc?

below are the two alternative invocations that I use, in libbsdmalloc with
the pcc from -current (you don't need MKLINT=no MKMAN=no I just added that
to cut down on output)
