Odd Behaviour

[MBB]

I'm using a PIC 16F1876.  In a subroutinre I have the following code.

If T_Sel = 1 then
AnemNS:
BTFSC PORTA,0; Rec_1
Goto Anem1b
A_Cnt = A_Cnt + 1; # of times Inst. Cycles repeated
BTFSC STATUS, C; Check fo Carry Bit
Goto Anem1B
Goto AnemNS
End If

'
If T_Sel = 2 then
AnemSN:
BTFSC PORTA,1; Rec_2
Goto Anem1b
A_Cnt = A_Cnt + 1
BTFSC STATUS, C
Goto Anem1B
Goto AnemSN
End If

'
If T_Sel = 3 then
AnemEW:
BTFSC PORTB,1; Rec_3
Goto Anem1b
A_Cnt = A_Cnt + 1
BTFSC STATUS, C
Goto Anem1B
Goto AnemEW
End If

'
If T_Sel = 4 then
AnemWE:
BTFSC PORTB,2; Rec_4
Goto Anem1b
A_Cnt = A_Cnt + 1

'BTFSC STATUS, C
'Goto Anem1B
Goto AnemWE
End If

'
Anem1b:

The above code works.  If I remove the comments marks in the T_Sel = 4 section from:

         BTFSC STATUS, C
Goto Anem1B

GCB still compiles the code with no errors and I can download it to the PIC BUT only the code under the T_Sel = 1 section  runs before the program freezes.

Does anyone know how to fix this?

In the above make that a PIC 16F876.
