--- Comment #1 from Jim Ingham <jingham at apple.com> ---
This is behaving as designed.  By default lldb's expression parser ignores
breakpoint hits when running the expression.  We did an informal survey and
most folks use function calling for the function call results, and didn't want
to stop just because that code happened to hit some breakpoint they had set.

If you want to stop at breakpoints in expressions, either use:

(lldb) expr -i 0 -- <EXPRESSION>

or if you always want to stop at breakpoints in expressions, do:

(lldb) settings set target.process.ignore-breakpoints-in-expressions 0

or change the "p" alias to be "expr -i 0 --"
