The difference to working code (test_code function) from gcc-4.4.5 is:

@@ -26,17 +26,18 @@
     ldah $1,fstat($0)        !dtprelhi
     ldq $26,0($30)
     lda $29,0($29)        !gpdisp!3
-    ldl $0,fstat($1)        !dtprello
-    addl $0,$9,$0
+    ldl $16,fstat($1)        !dtprello
+    addl $16,$9,$16
     ldq $9,8($30)
-    stl $0,fstat($1)        !dtprello
+    addl $31,$16,$0
+    stl $16,fstat($1)        !dtprello
     lda $30,16($30)
     ret $31,($26),1

Please note that $0 is used instead (extra addl is just a move from $16 to $0).
