So you need to build up an *array* of your parameters, not a string.
What you are trying to do does not, and cannot, work.

You have built up a string.  There is no way to delimit individual
parameters inside a string other than whitespace, and when you need
whitespace *inside* one of those parameters, you're stuck.  You need
an array instead, as others have already told you.

[code]
#!/bin/bash
...
$DEBUGGER my_executable "address@hidden"
[/code]
