User-defined commands, breakpoint "commands" hooks, parser bug?

User-defined commands, breakpoint "commands" hooks, parser bug?

[tqbf]

Hi. I've got a question about the way GDB processes user-defined
command definitions.

It seems that this is valid:

	define foo
		if bar
			c
		end
	end

But this is not valid:

	define foo
		b bar
		commands $bpnum
			c
		end
	end

In the first case, GDB recognizes the first "end" as terminating
the "if" statement. In the second, GDB doesn't recognize the "end"
as terminating the "commands" statement.

My version string reads "GNU gdb 5.0".

Thanks for any info you can give me.

Yes, this seems like a bug.

Thanks for letting us know.
