Wow.. that's a nasty trick....
And it should still work, also on Linux.
But I think that debuggers nowadays are more clever, they detect that
the breakpoint is actually self-inflicted, and so they decide to
continue. After all: the developer can have it's reasons to call this
interrupt, and the debugger should not influence normal execution.
I don't know if fpdebug has this same check. (I think it has, though,
but I'm not sure) If you are using a development Lazarus version you can
try to install the LazDebuggerFp package, and choose the 'Fpdebug
internal Dwarf-debugger' as debugger in the debugger-options. See what
happens if you do that...
