[Bug ada/41419] New: [450 regression] many new ACATs failures (breakpoint instruction in object)

---- A85013B CHECK THAT A SUBPROGRAM CAN BE RENAMED WITHIN ITS OWN BODY 
                AND THAT THE NEW NAME CAN BE USED IN A RENAMING
                DECLARATION.

Program received signal SIGTRAP, Trace/breakpoint trap.
0x88004be8 in system.task_primitives.operations.create_task (t=0x881a2e90, 
    wrapper=(system.address) 0x8800c7c8, stack_size=<value optimized out>, 
    priority=122) at s-taprop.adb:962

When I disassemble at 0x88004be8, I see this:

0x88004be0 <system__task_primitives__operations__create_task+136>:      bnez   
s4,0x88004bec <system__task_primitives__operations__create_task+148>
0x88004be4 <system__task_primitives__operations__create_task+140>:      divu   
zero,s5,s4
0x88004be8 <system__task_primitives__operations__create_task+144>:      break  
0x7

To confirm this was actually in the program executable, I objdump'ed it.
88004be0:       16800002        bnez    s4,88004bec
