BUS error ahead of my application code.

My application that written by Hitachi cobol85
and Pro*cobol have BUS error.
That AP was running well on HPUX10.20 env.
Now I am porting my all AP to HPUX11.00 for L2000.
I try to debug my AP by DDE assembler mode.
DDE said that

AP Entry
$START$ -->
_is_89_0 -->
_utssys
LDIL L%0xc0000000,r1
*** BE,L 4(sr7,r1),sr0,r31

When dde execute 2nd instruction of _utssys,
AP execute illegal virtual address.

DDE said

Can not read from Virtual address 00000000BFFFFE74.
Can not read from Virtual address 00000000BFFFFFFD.

:

Then AP execte ADDR C0000004 BREAK 0,8
instruction.

I found symbols ( $START$,_is_89_0,_utssys)
in /usr/ib/crt0.o .

It seems application program initialization failure.

This system have next patches
PHSS_22272,PHCO_22314

Now I try to install next patches.
PHSS_22514(ld) ,PHCO_23432 (libc 1020 compat) ,PHCO_22923(libc)
PHCO_23092,PHKL_20236

I want to have explanation of this BUS error.
What was wrong.

Thanks
