calling subroutine triggers interrupt

[Alexey]

Hello All,

Please advise if this is a known issue: I programmed PIC16F688 for interrupt on A2/INT on dropping edge which works fine, but I got a problem - every time I call any subroutine, it triggers the interrupt, even if the subroutine is empty like this:

SBRTN:
RETURN

every call to any subroutine (gosub ...) results execution of my interrupt handler subroutine.

Is this something known and caused by a common mistake?

Thank you,
Alexey
