The same happens if:
- the debug body is a compound statement
- I use a specific debug identifier
- I use version instead of debug
- the braces are removed from the catch body

The problem disappears if:
- I compile with the specified debug/version switch
- I add another statement before or after the debug statement (even if 
it's another debug statement)
