| compiler bug?? at clear_interrupt( INT_RBx ); |

Now I got trouble that I could not clear interrupt flag by using
clear_interrupt( INT_RBx );
I think this is compiler bug.
Please give me some advice, and show me how to solve it.
Device PIC16LF1937
software
MPLAB 8.46
CCS C PCM 4.104/4.105
I make isr as following.
| Code: |
void rb_isr( void )
{
ucDummy = input_b();
disable_interrupts( INT_RB0 );
disable_interrupts( INT_RB1 );
disable_interrupts( INT_RB2 );
disable_interrupts( INT_RB5 );
disable_interrupts( INT_RB6 );
disable_interrupts( INT_RB7 );
disable_interrupts( INT_RB );
clear_interrupt( INT_RB0 );
clear_interrupt( INT_RB1 );
clear_interrupt( INT_RB2 );
clear_interrupt( INT_RB3 );
clear_interrupt( INT_RB4 );
clear_interrupt( INT_RB5 );
clear_interrupt( INT_RB6 );
clear_interrupt( INT_RB7 );
clear_interrupt( INT_RB );
}

And I checked disassembly list, then
it seems like clear PIR2 register CCP2IF bit.

I think it sould be like as followings
| Code: |
922: clear_interrupt( INT_RB0 );
MOVLB 7
BCF 0x16, 0
923: clear_interrupt( INT_RB1 );
BCF 0x16, 1
924: clear_interrupt( INT_RB2 );
BCF 0x16, 2
925: clear_interrupt( INT_RB3 );
BCF 0x16, 3
926: clear_interrupt( INT_RB4 );
BCF 0x16, 4
927: clear_interrupt( INT_RB5 );
BCF 0x16, 5
928: clear_interrupt( INT_RB6 );
BCF 0x16, 6
929: clear_interrupt( INT_RB7 );
BCF 0x16, 7
