@labath something we noticed when finding this (and related bugs) is that
`frame var` carries a decent diagnostic
(int *) l_125 = <empty constant data>
and the expression parser returns just returns something not particularly
useful:
(lldb) p l_125
error: <lldb wrapper prefix>:43:31: no member named 'l_125' in namespace
'$__lldb_local_vars'
using $__lldb_local_vars::l_125;
~~~~~~~~~~~~~~~~~~~~^
error: <user expression 0>:1:1: use of undeclared identifier 'l_125'
l_125
From my testing infrastructure/fuzzing perspective the two are
indistinguishable, as the script I've written chokes on both, but it would be
better from an ergonomics point of view if `p` would return something
meaningful, if possible (even if there's a bug in lldb). Do you think it's
worth filing a PR? (also, cc: @teemperor for ideas as he spent a fair amount of
time working on the expression parser)
