Under some operating systems, breakpoints cannot be used in a program if

any other process is running that program. In this situation,

attempting to run or continue a program with a breakpoint causes
|

@value{GDBN} to print an error message:

Suspend @value{GDBN}, and copy the file containing your program to a new
|
||||
name. Resume @value{GDBN} and use the @code{exec-file} command to specify
|
||||
that @value{GDBN} should run your program under that name.
|

Then start your program again.
