That's exactly what I'm seeing on SPARC/Solaris and SPARC/Linux.  HP's patch 
has introduced

FAIL: vers2
FAIL: vers26b1
FAIL: vers26b2
FAIL: vers26b3

in the ld testsuite because of this problem:
http://sources.redhat.com/ml/binutils/2004-10/msg00029.html
http://sources.redhat.com/ml/binutils/2004-11/msg00159.html
