520.0. "debugger skips lines" by KAOFS::M_VALLEE (csc hull canada) Wed Jun 04 1997 12:43

    vc++ 4.1 on alpha
    
    When running the debugger on a program it skips lines in the program so
    you can't debug the whole thing.Tried to reproduce on intel platform 
    and can't we only see this problem on alpha.

	It also may happen with optimized code. if (condition) variable = 1; If variable is allocated in a register, the whole statement can be reduced to one cmov instruction like: cmoveq condition, 1, variable This gets attributed to one or the other line (I don't remember which) and it's not possible to set a breakpoint on the other.
