Could you please try to find out: run sum on /usr/ccs/lib/cmplrs/cc/ld and
grep for the same path in /usr/.smdb./*.inv.

I've been completely unable to reproduce this, with any ld from V5.1,
V5.1A, or patch kits for those O/S versions.

I've included a test case (extracted from the g++.dg/special/conpr-3.C
test) below.  I get:
